Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective.

Blue has been an important colour in art and decoration since ancient times. The semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and later, in the Renaissance, to make the pigment ultramarine, the most expensive of all pigments. In the eighth century Chinese artists used cobalt blue to colour fine blue and white porcelain. In the Middle Ages, European artists used it in the windows of cathedrals. Europeans wore clothing coloured with the vegetable dye woad until it was replaced by the finer indigo from America. In the 19th century, synthetic blue dyes and pigments gradually replaced organic dyes and mineral pigments. Dark blue became a common colour for military uniforms and later, in the late 20th century, for business suits. Because blue has commonly been associated with harmony, it was chosen as the colour of the flags of the United Nations and the European Union.

Surveys in the US and Europe show that blue is the colour most commonly associated with harmony, faithfulness, confidence, distance, infinity, the imagination, cold, and occasionally with sadness. In US and European public opinion polls it is the most popular colour, chosen by almost half of both men and women as their favourite colour. The same surveys also showed that blue was the colour most associated with the masculine, just ahead of black, and was also the colour most associated with intelligence, knowledge, calm and concentration.

Blue is the colour of light between violet and green on the visible spectrum. Hues of blue include indigo and ultramarine, closer to violet; pure blue, without any mixture of other colours; Cyan, which is midway in the spectrum between blue and green, and the other blue-greens turquoise, teal, and aquamarine.

Blue also varies in shade or tint; darker shades of blue contain black or grey, while lighter tints contain white. Darker shades of blue include ultramarine, cobalt blue, navy blue, and Prussian blue; while lighter tints include sky blue, azure, and Egyptian blue. (For a more complete list see the List of colours).

Blue pigments were originally made from minerals such as lapis lazuli, cobalt and azurite, and blue dyes were made from plants; usually woad in Europe, and Indigofera tinctoria, or true indigo, in Asia and Africa. Today most blue pigments and dyes are made by a chemical process.

The modern English word blue comes from Middle English bleu or blewe, from the Old French bleu, a word of Germanic origin, related to the Old High German word blao (meaning shimmering, lustrous). In heraldry, the word azure is used for blue.

In Russian and some other languages, there is no single word for blue, but rather different words for light blue (голубой, goluboj) and dark blue (синий, sinij). See Colour term.

Several languages, including Japanese, Thai, and Lakota Sioux, use the same word to describe blue and green. For example, in Vietnamese, the colour of both tree leaves and the sky is xanh. In Japanese, the word for blue (青 ao) is often used for colours that English speakers would refer to as green, such as the colour of a traffic signal meaning "go". (For more on this subject, see Distinguishing blue from green in language)

Linguistic research indicates that languages do not begin by having a word for the colour blue. Colour names often developed individually in natural languages, typically beginning with black and white (or dark and light), and then adding red, and only much later – usually as the last main category of colour accepted in a language – adding the colour blue, probably when blue pigments could be manufactured reliably in the culture using that language.

Human eyes perceive blue when observing light which has a dominant wavelength of roughly 450–495 nanometres. Blues with a higher frequency and thus a shorter wavelength gradually look more violet, while those with a lower frequency and a longer wavelength gradually appear more green. Pure blue, in the middle, has a wavelength of 470 nanometres.

Isaac Newton included blue as one of the seven colours in his first description the visible spectrum. He chose seven colours because that was the number of notes in the musical scale, which he believed was related to the optical spectrum. He included indigo, the hue between blue and violet, as one of the separate colours, though today it is usually considered a hue of blue.

In painting and traditional colour theory, blue is one of the three primary colours of pigments (red, yellow, blue), which can be mixed to form a wide gamut of colours. Red and blue mixed together form violet, blue and yellow together form green. Mixing all three primary colours together produces a dark grey. From the Renaissance onwards, painters used this system to create their colours. (See RYB colour system.)

The RYB model was used for colour printing by Jacob Christoph Le Blon as early as 1725. Later, printers discovered that more accurate colours could be created by using combinations of magenta, cyan, yellow and black ink, put onto separate inked plates and then overlaid one at a time onto paper. This method could produce almost all the colours in the spectrum with reasonable accuracy.

In the 19th century the Scottish physicist James Clerk Maxwell found a new way of explaining colours, by the wavelength of their light. He showed that white light could be created by combining red, blue and green light, and that virtually all colours could be made by different combinations of these three colours. His idea, called additive colour or the RGB colour model, is used today to create colours on televisions and computer screens. The screen is covered by tiny pixels, each with three fluorescent elements for creating red, green and blue light. If the red, blue and green elements all glow at once, the pixel looks white. As power is applied to individual colored LEDs on the screen, each forming a pixel, the pixels light up with their individual colors, composing a complete picture on the screen.

Additive colour mixing. The projection of primary colour lights on a screen shows secondary colours where two overlap; the combination red, green, and blue each in full intensity makes white.

On the HSV colour wheel, the complement of blue is yellow; that is, a colour corresponding to an equal mixture of red and green light. On a colour wheel based on traditional colour theory (RYB) where blue was considered a primary colour, its complementary colour is considered to be orange (based on the Munsell colour wheel).

Blue pigments were made from minerals, especially lapis lazuli and azurite (Cu

. These minerals were crushed, ground into powder, and then mixed with a quick-drying binding agent, such as egg yolk (tempera painting); or with a slow-drying oil, such as linseed oil, for oil painting. To make blue stained glass, cobalt blue (cobalt(II) aluminate: CoAl

Natural dyes to colour cloth and tapestries were made from plants. Woad and true indigo were used to produce indigo dye used to colour fabrics blue or indigo. Since the 18th century, natural blue dyes have largely been replaced by synthetic dyes.

"Reflex blue" used to be the name of a common blue pigment in ink manufacturing. In the 1960s, the name was adopted into the proprietary Pantone Matching System (PMS) to refer to this specific pigment. Pantone "Reflex Blue" has the particularity of being identified only by this name, and not by a number code.

Lapis lazuli, mined in Afghanistan for more than three thousand years, was used for jewellery and ornaments, and later was crushed and powdered and used as a pigment. The more it was ground, the lighter the blue colour became.

Azurite, a common mineral, was used as a pigment from ancient times, although it degrades readily and thus inferior.

Natural ultramarine, made by grinding and purifying lapis lazuli, was the finest available blue pigment in the Middle Ages and the Renaissance. It was extremely expensive, and in Italian Renaissance art, it was often reserved for the robes of the Virgin Mary.

Egyptian blue, the first artificial pigment, produced in the third millennium BC in Ancient Egypt by grinding sand, copper and natron, and then heating them. It was often used in tomb paintings and funereal objects to protect the dead in their afterlife.

Ground azurite was often in Renaissance used as a substitute for the much more expensive lapis lazuli. It made a rich blue, but was unstable and could turn dark green over time.

Cerulean, produced by combining copper and cobalt oxide, is used to make a sky blue colour. Like azurite, it is not a long-lived pigment.

Cobalt blue. Cobalt is used to make the deep blue stained glass windows, such as those in Gothic cathedrals. It is used in Chinese porcelain beginning in the T'ang Dynasty. In 1799 a French chemist, Louis Jacques Thénard, made a synthetic cobalt blue pigment which became immensely popular with painters.

Indigo dye originally isolated from the woad, Indigofera tinctoria, a plant common in Asia and Africa but little known in Europe until the 15th century. Its importation into Europe revolutionised the colour of clothing. It also became the colour used in blue denim and jeans. Nearly all indigo dye produced today is synthetic.

Of the colours in the visible spectrum of light, blue has a very short wavelength, while red has the longest wavelength. When sunlight passes through the atmosphere, the blue wavelengths are scattered more widely by the oxygen and nitrogen molecules, and more blue comes to our eyes. This effect is called Rayleigh scattering, after Lord Rayleigh, the British physicist who discovered it. It was confirmed by Albert Einstein in 1911.

Near sunrise and sunset, most of the light we see comes in nearly tangent to the Earth's surface, so that the light's path through the atmosphere is so long that much of the blue and even green light is scattered out, leaving the sun rays and the clouds it illuminates red. Therefore, when looking at the sunset and sunrise, the colour red is more perceptible than any of the other colours.

The sea is seen as blue for largely the same reason: the water absorbs the longer wavelengths of red and reflects and scatters the blue, which comes to the eye of the viewer. The colour of the sea is also affected by the colour of the sky, reflected by particles in the water; and by algae and plant life in the water, which can make it look green; or by sediment, which can make it look brown.

The farther away an object is, the more blue it often appears to the eye. For example, mountains in the distance often appear blue. This is the effect of atmospheric perspective; the farther an object is away from the viewer, the less contrast there is between the object and its background colour, which is usually blue. In a painting where different parts of the composition are blue, green and red, the blue will appear to be more distant, and the red closer to the viewer. The cooler a colour is, the more distant it seems.

Blue light is scattered more than other wavelengths by the gases in the atmosphere, giving the Earth a blue halo when seen from space.

An example of aerial, or atmospheric perspective. Objects become more blue and lighter in colour the farther they are from the viewer, because of Rayleigh scattering.

Under the sea, red and other light with longer wavelengths is absorbed, so white objects appear blue. The deeper the observer goes, the darker the blue becomes. In the open sea, only about one per cent of light penetrates to a depth of 200 metres. (See underwater and euphotic depth)

Blue giants are hot and luminous stars with surface temperatures exceeding 10,000 K. The largest blue supergiant stars are extremely massive and energetic, and are usually unstable. They are generally short-lived, either exploding in a supernova or periodically shedding their outer layers to become red giants.

Blue eyes do not actually contain any blue pigment. Eye colour is determined by two factors: the pigmentation of the eye's iris and the scattering of light by the turbid medium in the stroma of the iris. In humans, the pigmentation of the iris varies from light brown to black. The appearance of blue, green, and hazel eyes results from the Tyndall scattering of light in the stroma, an optical effect similar to what accounts for the blueness of the sky. The irises of the eyes of people with blue eyes contain less dark melanin than those of people with brown eyes, which means that they absorb less short-wavelength blue light, which is instead reflected out to the viewer. Eye colour also varies depending on the lighting conditions, especially for lighter-coloured eyes.

Blue eyes are most common in Ireland, the Baltic Sea area and Northern Europe, and are also found in Eastern, Central, and Southern Europe. Blue eyes are also found in parts of Western Asia, most notably in Afghanistan, Syria, Iraq, and Iran. In Estonia, 99% of people have blue eyes. In Denmark 30 years ago, only 8% of the population had brown eyes, though through immigration, today that number is about 11%. In Germany, about 75% have blue eyes.

In the United States, as of 2006, one out of every six people, or 16.6% of the total population, and 22.3% of the white population, have blue eyes, compared with about half of Americans born in 1900, and a third of Americans born in 1950. Blue eyes are becoming less common among American children. In the US, boys are 3–5 per cent more likely to have blue eyes than girls.

Lasers emitting in the blue region of the spectrum became widely available to the public in 2010 with the release of inexpensive high-powered 445–447 nm laser diode technology. Previously the blue wavelengths were accessible only through DPSS which are comparatively expensive and inefficient, however these technologies are still widely used by the scientific community for applications including optogenetics, Raman spectroscopy, and particle image velocimetry, due to their superior beam quality. Blue gas lasers are also still commonly used for holography, DNA sequencing, optical pumping, and other scientific and medical applications.

Blue was a latecomer among colours used in art and decoration, as well as language and literature. Reds, blacks, browns, and ochres are found in cave paintings from the Upper Paleolithic period, but not blue. Blue was also not used for dyeing fabric until long after red, ochre, pink and purple. This is probably due to the perennial difficulty of making good blue dyes and pigments. The earliest known blue dyes were made from plants – woad in Europe, indigo in Asia and Africa, while blue pigments were made from minerals, usually either lapis lazuli or azurite.

Lapis lazuli, a semi-precious stone, has been mined in Afghanistan for more than three thousand years, and was exported to all parts of the ancient world. Blue glazed faience ornaments have been found to have been produced during 4th millennium civilization Indus Valley Civilization (present day India and Pakistan). In Iran and Mesopotamia, it was used to make jewellery and vessels. In Egypt, it was used for the eyebrows on the funeral mask of King Tutankhamun (1341–1323 BC). Importing lapis lazuli by caravan across the desert from Afghanistan to Egypt was very expensive. Beginning in about 2500 BC, the ancient Egyptians began to produce their own blue pigment known as Egyptian blue by grinding silica, lime, copper, and alkalai, and heating it to 800 or 900 °C (1,470 or 1,650 °F). This is considered the first synthetic pigment. Egyptian blue was used to paint wood, papyrus and canvas, and was used to colour a glaze to make faience beads, inlays, and pots. It was particularly used in funeral statuary and figurines and in tomb paintings. Blue was considered a beneficial colour which would protect the dead against evil in the afterlife. Blue dye was also used to colour the cloth in which mummies were wrapped.

In Egypt blue was associated with the sky and with divinity. The Egyptian god Amun could make his skin blue so that he could fly, invisible, across the sky. Blue could also protect against evil; many people around the Mediterranean still wear a blue amulet, representing the eye of God, to protect them from misfortune. Blue glass was manufactured in Mesopotamia and Egypt as early as 2500 BC, using the same copper ingredients as Egyptian blue pigment. They also added cobalt, which produced a deeper blue, the same blue produced in the Middle Ages in the stained glass windows of the cathedrals of Saint-Denis and Chartres. The Ishtar Gate of ancient Babylon (604–562 BC) was decorated with deep blue glazed bricks used as a background for pictures of lions, dragons and aurochs.

The ancient Greeks classified colours by whether they were light or dark, rather than by their hue. The Greek word for dark blue, kyaneos, could also mean dark green, violet, black or brown. The ancient Greek word for a light blue, glaukos, also could mean light green, grey, or yellow. The Greeks imported indigo dye from India, calling it indikon. They used Egyptian blue in the wall paintings of Knossos, in Crete, (2100 BC). It was not one of the four primary colours for Greek painting described by Pliny the Elder (red, yellow, black, and white), but nonetheless it was used as a background colour behind the friezes on Greek temples and to colour the beards of Greek statues.

The Romans also imported indigo dye, but blue was the colour of working class clothing; the nobles and rich wore white, black, red or violet. Blue was considered the colour of mourning, and the colour of barbarians. Julius Caesar reported that the Celts and Germans dyed their faces blue to frighten their enemies, and tinted their hair blue when they grew old. Nonetheless, the Romans made extensive use of blue for decoration. According to Vitruvius, they made dark blue pigment from indigo, and imported Egyptian blue pigment. The walls of Roman villas in Pompeii had frescoes of brilliant blue skies, and blue pigments were found in the shops of colour merchants. The Romans had many different words for varieties of blue, including caeruleus, caesius, glaucus, cyaneus, lividus, venetus, aerius, and ferreus, but two words, both of foreign origin, became the most enduring; blavus, from the Germanic word blau, which eventually became bleu or blue; and azureus, from the Arabic word lazaward, which became azure.

Dark blue was widely used in the decoration of churches in the Byzantine Empire. In Byzantine art Christ and the Virgin Mary usually wore dark blue or purple. Blue was used as a background colour representing the sky in the magnificent mosaics which decorated Byzantine churches.

In the Islamic world, blue was of secondary importance to green, believed to be the favourite colour of the Prophet Mohammed. At certain times in Moorish Spain and other parts of the Islamic world, blue was the colour worn by Christians and Jews, because only Muslims were allowed to wear white and green. Dark blue and turquoise decorative tiles were widely used to decorate the facades and interiors of mosques and palaces from Spain to Central Asia. Lapis lazuli pigment was also used to create the rich blues in Persian miniatures.

In the art and life of Europe during the early Middle Ages, blue played a minor role. The nobility wore red or purple, while only the poor wore blue clothing, coloured with poor-quality dyes made from the woad plant. Blue played no part in the rich costumes of the clergy or the architecture or decoration of churches. This changed dramatically between 1130 and 1140 in Paris, when the Abbe Suger rebuilt the Saint Denis Basilica. He installed stained glass windows coloured with cobalt, which, combined with the light from the red glass, filled the church with a bluish violet light. The church became the marvel of the Christian world, and the colour became known as the "bleu de Saint-Denis". In the years that followed even more elegant blue stained glass windows were installed in other churches, including at Chartres Cathedral and Sainte-Chapelle in Paris.

Another important factor in the increased prestige of the colour blue in the 12th century was the veneration of the Virgin Mary, and a change in the colours used to depict her clothing. In earlier centuries her robes had usually been painted in sombre black, grey, violet, dark green or dark blue. In the 12th century the Roman Catholic Church dictated that painters in Italy (and the rest of Europe consequently) to paint the Virgin Mary with the new most expensive pigment imported from Asia; ultramarine.[citation needed] Blue became associated with holiness, humility and virtue.

Ultramarine was made from lapis lazuli, from the mines of Badakshan, in the mountains of Afghanistan, near the source of the Oxus River. The mines were visited by Marco Polo in about 1271; he reported, "here is found a high mountain from which they extract the finest and most beautiful of blues." Ground lapis was used in Byzantine manuscripts as early as the 6th century, but it was impure and varied greatly in colour. Ultramarine refined out the impurities through a long and difficult process, creating a rich and deep blue. It was called bleu outremer in French and blu oltremare in Italian, since it came from the other side of the sea. It cost far more than any other colour, and it became the luxury colour for the Kings and Princes of Europe.

King Louis IX of France, better known as Saint Louis (1214–1270), became the first king of France to regularly dress in blue. This was copied by other nobles. Paintings of the mythical King Arthur began to show him dressed in blue. The coat of arms of the kings of France became an azure or light blue shield, sprinkled with golden fleur-de-lis or lilies. Blue had come from obscurity to become the royal colour.

Once blue became the colour of the king, it also became the colour of the wealthy and powerful in Europe. In the Middle Ages in France and to some extent in Italy, the dyeing of blue cloth was subject to license from the crown or state. In Italy, the dyeing of blue was assigned to a specific guild, the tintori di guado, and could not be done by anyone else without severe penalty. The wearing of blue implied some dignity and some wealth.

Besides ultramarine, several other blues were widely used in the Middle Ages and later in the Renaissance. Azurite, a form of copper carbonate, was often used as a substitute for ultramarine. The Romans used it under the name lapis armenius, or Armenian stone. The British called it azure of Amayne, or German azure. The Germans themselves called it bergblau, or mountain stone. It was mined in France, Hungary, Spain and Germany, and it made a pale blue with a hint of green, which was ideal for painting skies. It was a favourite background colour of the German painter Albrecht Dürer.

Another blue often used in the Middle Ages was called tournesol or folium. It was made from the plant Crozophora tinctoria, which grew in the south of France. It made a fine transparent blue valued in medieval manuscripts.

Another common blue pigment was smalt, which was made by grinding blue cobalt glass into a fine powder. It made a deep violet blue similar to ultramarine, and was vivid in frescoes, but it lost some of its brilliance in oil paintings. It became especially popular in the 17th century, when ultramarine was difficult to obtain. It was employed at times by Titian, Tintoretto, Veronese, El Greco, Van Dyck, Rubens and Rembrandt.

In the Renaissance, a revolution occurred in painting; artists began to paint the world as it was actually seen, with perspective, depth, shadows, and light from a single source. Artists had to adapt their use of blue to the new rules. In medieval paintings, blue was used to attract the attention of the viewer to the Virgin Mary, and identify her. In Renaissance paintings, artists tried to create harmonies between blue and red, lightening the blue with lead white paint and adding shadows and highlights. Raphael was a master of this technique, carefully balancing the reds and the blues so no one colour dominated the picture.

Ultramarine was the most prestigious blue of the Renaissance, and patrons sometimes specified that it be used in paintings they commissioned. The contract for the Madone des Harpies by Andrea del Sarto (1514) required that the robe of the Virgin Mary be coloured with ultramarine costing "at least five good florins an ounce." Good ultramarine was more expensive than gold; in 1508 the German painter Albrecht Dürer reported in a letter that he had paid twelve ducats – the equivalent of forty-one grams of gold – for just thirty grams of ultramarine.

Often painters or clients saved money by using less expensive blues, such as azurite smalt, or pigments made with indigo, but this sometimes caused problems. Pigments made from azurite were less expensive, but tended to turn dark and green with time. An example is the robe of the Virgin Mary in The Madonna and Child Enthroned with Saints by Raphael in the Metropolitan Museum in New York. The Virgin Mary's azurite blue robe has degraded into a greenish-black.

The introduction of oil painting changed the way colours looked and how they were used. Ultramarine pigment, for instance, was much darker when used in oil painting than when used in tempera painting, in frescoes. To balance their colours, Renaissance artists like Raphael added white to lighten the ultramarine. The sombre dark blue robe of the Virgin Mary became a brilliant sky blue. Titian created his rich blues by using many thin glazes of paint of different blues and violets which allowed the light to pass through, which made a complex and luminous colour, like stained glass. He also used layers of finely ground or coarsely ground ultramarine, which gave subtle variations to the blue.

Giotto was one of the first Italian Renaissance painters to use ultramarine, here in the murals of the Arena Chapel in Padua (circa 1305).

Throughout the 14th and 15th centuries, the robes of the Virgin Mary were painted with ultramarine. This is The Virgin of Humility by Fra Angelico (about 1430). Blue fills the picture.

In the Madonna of the Meadow (1506), Raphael used white to soften the ultramarine blue of Virgin Mary's robes to balance the red and blue, and to harmonise with the rest of the picture.

Titian used an ultramarine sky and robes to give depth and brilliance to his Bacchus and Ariadne (1520–1523)

In this painting of The Madonna and Child Enthroned with Saints an early work by Raphael in the Metropolitan Museum of Art, the blue cloak of the Virgin Mary has turned a green-black. It was painted with less-expensive azurite.

The Très Riches Heures du Duc de Berry was the most important illuminated manuscript of the 15th century. The blue was the extravagantly expensive ultramarine.

In about the 9th century, Chinese artisans abandoned the Han blue colour they had used for centuries, and began to use cobalt blue, made with cobalt salts of alumina, to manufacture fine blue and white porcelain, The plates and vases were shaped, dried, the paint applied with a brush, covered with a clear glaze, then fired at a high temperature. Beginning in the 14th century, this type of porcelain was exported in large quantity to Europe where it inspired a whole style of art, called Chinoiserie. European courts tried for many years to imitate Chinese blue and white porcelain, but only succeeded in the 18th century after a missionary brought the secret back from China.

Other famous white and blue patterns appeared in Delft, Meissen, Staffordshire, and Saint Petersburg, Russia.

The pastel industry was threatened in the 15th century by the arrival from India of the same dye (indigo), obtained from a shrub widely grown in Asia. The Asian indigo dye precursors is more readily obtained. In 1498, Vasco da Gama opened a trade route to import indigo from India to Europe. In India, the indigo leaves were soaked in water, fermented, pressed into cakes, dried into bricks, then carried to the ports London, Marseille, Genoa, and Bruges. Later, in the 17th century, the British, Spanish, and Dutch established indigo plantations in Jamaica, South Carolina, the Virgin Islands and South America, and began to import American indigo to Europe.

The countries with large and prosperous pastel industries tried to block the use of indigo. One government in Germany outlawed the use of indigo in 1577, describing it as a "pernicious, deceitful and corrosive substance, the Devil's dye." In France, Henry IV, in an edict of 1609, forbade under pain of death the use of "the false and pernicious Indian drug". It was forbidden in England until 1611, when British traders established their own indigo industry in India and began to import it into Europe.

The efforts to block indigo were in vain; the quality of indigo blue was too high and the price too low for pastel made from woad to compete. In 1737 both the French and German governments finally allowed the use of indigo. This ruined the dye industries in Toulouse and the other cities that produced pastel, but created a thriving new indigo commerce to seaports such as Bordeaux, Nantes and Marseille.

Another war of the blues took place at the end of the 19th century, between indigo and synthetic indigo, discovered in 1868 by the German chemist Johann Friedrich Wilhelm Adolf von Baeyer. The German chemical firm BASF put the new dye on the market in 1897, in direct competition with the British-run indigo industry in India, which produced most of the world's indigo. In 1897 Britain sold ten thousand tons of natural indigo on the world market, while BASF sold six hundred tons of synthetic indigo. The British industry took measures to ensure their economic viability with the new BASF dye, but it was unable to compete; the synthetic indigo was more pure, made a more lasting blue, and was not dependent upon good or bad harvests. In 1911, India sold only 660 tons of natural indigo, while BASF sold 22,000 tons of synthetic indigo. In 2002, more than 38,000 tons of synthetic indigo was produced, often for the production of blue jeans.

Isatis tinctoria, or woad, was the main source of blue dye in Europe from ancient times until the arrival of indigo from Asia and America. It was processed into a paste called pastel.

Indigofera tinctoria, a tropical shrub, is the main source of indigo dye. The chemical composition of indigo dye is the same as that of woad, but the colour is more intense.

Cakes of indigo. The leaf has been soaked in water, fermented, mixed with lye or another base, then pressed into cakes and dried, ready for export.

In the 17th century, Frederick William, Elector of Brandenburg, was one of the first rulers to give his army blue uniforms. The reasons were economic; the German states were trying to protect their pastel dye industry against competition from imported indigo dye. When Brandenburg became the Kingdom of Prussia in 1701, the uniform colour was adopted by the Prussian army. Most German soldiers wore dark blue uniforms until the First World War, with the exception of the Bavarians, who wore light blue.

In 1748, the British uniform for naval officers was officially established as an embroidered coat of the colour then called marine blue, now known as navy blue. In the late 18th century, the blue uniform became a symbol of liberty and revolution. In October 1774, even before the United States declared its independence, George Mason and one hundred Virginia neighbours of George Washington organised a voluntary militia unit (the Fairfax County Independent Company of Volunteers) and elected Washington the honorary commander. For their uniforms they chose blue and buff, the colours of the Whig Party, the opposition party in England, whose policies were supported by George Washington and many other patriots in the American colonies.

When the Continental Army was established in 1775 at the outbreak of the American Revolution, the first Continental Congress declared that the official uniform colour would be brown, but this was not popular with many militias, whose officers were already wearing blue. In 1778 the Congress asked George Washington to design a new uniform, and in 1779 Washington made the official colour of all uniforms blue and buff. Blue continued to be the colour of the field uniform of the US Army until 1902, and is still the colour of the dress uniform.

In France the Gardes Françaises, the elite regiment which protected Louis XVI, wore dark blue uniforms with red trim. In 1789, the soldiers gradually changed their allegiance from the king to the people, and they played a leading role in the storming of the Bastille. Blue became the colour of the revolutionary armies, opposed to the white uniforms of the Royalists and the Austrians.

Napoleon Bonaparte abandoned many of the doctrines of the French Revolution but he kept blue as the uniform colour for his army, although he had great difficulty obtaining the blue dye, since the British held naval control in the Atlantic and blocked the importation of indigo to France. Napoleon was forced to dye uniforms with woad, which had an inferior blue colour. The French army wore a dark blue uniform coat with red trousers until 1915, when it was found to be a too visible target on the battlefields of World War I. It was replaced with uniforms of a light blue-grey colour called horizon blue.

Blue was the colour of liberty and revolution in the 18th century, but in the 19th it increasingly became the colour of government authority, the uniform colour of policemen and other public servants. It was considered serious and authoritative, without being menacing. In 1829, when Robert Peel created the first London Metropolitan Police, he made the colour of the uniform jacket a dark, almost black blue, to make the policemen look different from the red coated soldiers, who had on occasion been used to enforce order. The traditional blue jacket with silver buttons of the London "bobbie" was not abandoned until the mid-1990s, when it was replaced for all but formal occasions by a jumper or sweater of the colour officially known as NATO blue.

The New York City Police Department, modelled after the London Metropolitan Police, was created in 1844, and in 1853, they were officially given a navy blue uniform, the colour they wear today.

Navy blue is one of the most popular school uniform colours, with the Toronto Catholic District School Board adopting a dress code policy which requires students system-wide to wear white tops and navy blue bottoms.

Elector Frederic William of Brandenburg gave his soldiers blue uniforms (engraving from 1698). When Brandenburg became the Kingdom of Prussia in 1701, blue became the uniform colour of the Prussian Army.

During the 17th and 18th centuries, chemists in Europe tried to discover a way to create synthetic blue pigments, avoiding the expense of importing and grinding lapis lazuli, azurite and other minerals. The Egyptians had created a synthetic colour, Egyptian blue, three thousand years BC, but the formula had been lost. The Chinese had also created synthetic pigments, but the formula was not known in the west.

In 1709 a German druggist and pigment maker named Johann Jacob Diesbach accidentally discovered a new blue while experimenting with potassium and iron sulphides. The new colour was first called Berlin blue, but later became known as Prussian blue. By 1710 it was being used by the French painter Antoine Watteau, and later his successor Nicolas Lancret. It became immensely popular for the manufacture of wallpaper, and in the 19th century was widely used by French impressionist painters.

Beginning in the 1820s, Prussian blue was imported into Japan through the port of Nagasaki. It was called bero-ai, or Berlin blue, and it became popular because it did not fade like traditional Japanese blue pigment, ai-gami, made from the dayflower. Prussian blue was used by both Hokusai, in his famous wave paintings, and Hiroshige.

In 1824 the Societé pour l'Encouragement d'Industrie in France offered a prize for the invention of an artificial ultramarine which could rival the natural colour made from lapis lazuli. The prize was won in 1826 by a chemist named Jean Baptiste Guimet, but he refused to reveal the formula of his colour. In 1828, another scientist, Christian Gmelin then a professor of chemistry in Tübingen, found the process and published his formula. This was the beginning of new industry to manufacture artificial ultramarine, which eventually almost completely replaced the natural product.

In 1878 a German chemist named a. Von Baeyer discovered a synthetic substitute for indigotine, the active ingredient of indigo. This product gradually replaced natural indigo, and after the end of the First World War, it brought an end to the trade of indigo from the East and West Indies.

In 1901 a new synthetic blue dye, called Indanthrone blue, was invented, which had even greater resistance to fading during washing or in the sun. This dye gradually replaced artificial indigo, whose production ceased in about 1970. Today almost all blue clothing is dyed with an indanthrone blue.

Thomas Gainsborough's The Blue Boy includes "the lavish lapis lazuli, the darker indigo pigment and the paler cobalt."

The 19th-century Japanese woodblock artist Hokusai used Prussian blue, a synthetic colour imported from Europe, in his wave paintings, such as in The Great Wave off Kanagawa.

A synthetic indigo dye factory in Germany in 1890. The manufacture of this dye ended the trade in indigo from America and India that had begun in the 15th century.

The invention of new synthetic pigments in the 18th and 19th centuries considerably brightened and expanded the palette of painters. J. M. W. Turner experimented with the new cobalt blue, and of the twenty colours most used by the Impressionists, twelve were new and synthetic colours, including cobalt blue, ultramarine and cerulean blue.

Another important influence on painting in the 19th century was the theory of complementary colours, developed by the French chemist Michel Eugene Chevreul in 1828 and published in 1839. He demonstrated that placing complementary colours, such as blue and yellow-orange or ultramarine and yellow, next to each other heightened the intensity of each colour "to the apogee of their tonality." In 1879 an American physicist, Ogden Rood, published a book charting the complementary colours of each colour in the spectrum. This principle of painting was used by Claude Monet in his Impression – Sunrise – Fog (1872), where he put a vivid blue next to a bright orange sun, (1872) and in Régate à Argenteuil (1872), where he painted an orange sun against blue water. The colours brighten each other. Renoir used the same contrast of cobalt blue water and an orange sun in Canotage sur la Seine (1879–1880). Both Monet and Renoir liked to use pure colours, without any blending.

Monet and the impressionists were among the first to observe that shadows were full of colour. In his La Gare Saint-Lazare, the grey smoke, vapour and dark shadows are actually composed of mixtures of bright pigment, including cobalt blue, cerulean blue, synthetic ultramarine, emerald green, Guillet green, chrome yellow, vermilion and ecarlate red. Blue was a favourite colour of the impressionist painters, who used it not just to depict nature but to create moods, feelings and atmospheres. Cobalt blue, a pigment of cobalt oxide-aluminium oxide, was a favourite of Auguste Renoir and Vincent van Gogh. It was similar to smalt, a pigment used for centuries to make blue glass, but it was much improved by the French chemist Louis Jacques Thénard, who introduced it in 1802. It was very stable but extremely expensive. Van Gogh wrote to his brother Theo, "'Cobalt [blue] is a divine colour and there is nothing so beautiful for putting atmosphere around things ..."

Van Gogh described to his brother Theo how he composed a sky: "The dark blue sky is spotted with clouds of an even darker blue than the fundamental blue of intense cobalt, and others of a lighter blue, like the bluish white of the Milky Way ... the sea was very dark ultramarine, the shore a sort of violet and of light red as I see it, and on the dunes, a few bushes of prussian blue."

Claude Monet used several recently invented colours in his Gare Saint-Lazare (1877). He used cobalt blue, invented in 1807, cerulean blue invented in 1860, and French ultramarine, first made in 1828.

The Umbrellas, by Pierre Auguste-Renoir. (1881 and 1885). Renoir used cobalt blue for right side of the picture, but used the new synthetic ultramarine introduced in the 1870s, when he added two figures to left of the picture a few years later.

In Vincent van Gogh's Irises, the blue irises are placed against their complementary colour, yellow-orange.

Van Gogh's Starry Night Over the Rhône (1888). Blue used to create a mood or atmosphere. A cobalt blue sky, and cobalt or ultramarine water.

Wheatfield Under Thunderclouds (July 1890), one of the last paintings by Vincent van Gogh. He wrote of cobalt blue, "there is nothing so beautiful for putting atmosphere around things."

Blue had first become the high fashion colour of the wealthy and powerful in Europe in the 13th century, when it was worn by Louis IX of France, better known as Saint Louis (1214–1270). Wearing blue implied dignity and wealth, and blue clothing was restricted to the nobility. However, blue was replaced by black as the power colour in the 14th century, when European princes, and then merchants and bankers, wanted to show their seriousness, dignity and devoutness (see Black).

Blue gradually returned to court fashion in the 17th century, as part of a palette of peacock-bright colours shown off in extremely elaborate costumes. The modern blue business suit has its roots in England in the middle of the 17th century. Following the London plague of 1665 and the London fire of 1666, King Charles II of England ordered that his courtiers wear simple coats, waistcoats and breeches, and the palette of colours became blue, grey, white and buff. Widely imitated, this style of men's fashion became almost a uniform of the London merchant class and the English country gentleman.

During the American Revolution, the leader of the Whig Party in England, Charles James Fox, wore a blue coat and buff waistcoat and breeches, the colours of the Whig Party and of the uniform of George Washington, whose principles he supported. The men's suit followed the basic form of the military uniforms of the time, particularly the uniforms of the cavalry.

In the early 19th century, during the Regency of the future King George IV, the blue suit was revolutionised by a courtier named George Beau Brummel. Brummel created a suit that closely fitted the human form. The new style had a long tail coat cut to fit the body and long tight trousers to replace the knee-length breeches and stockings of the previous century. He used plain colours, such as blue and grey, to concentrate attention on the form of the body, not the clothes. Brummel observed, "If people turn to look at you in the street, you are not well dressed." This fashion was adopted by the Prince Regent, then by London society and the upper classes. Originally the coat and trousers were different colours, but in the 19th century the suit of a single colour became fashionable. By the late 19th century the black suit had become the uniform of businessmen in England and America. In the 20th century, the black suit was largely replaced by the dark blue or grey suit.

King Louis IX of France (on the right, with Pope Innocent) was the first European king to wear blue. It quickly became the colour of the nobles and wealthy.

At the beginning of the 20th century, many artists recognised the emotional power of blue, and made it the central element of paintings. During his Blue Period (1901–1904) Pablo Picasso used blue and green, with hardly any warm colours, to create a melancholy mood. In Russia, the symbolist painter Pavel Kuznetsov and the Blue Rose art group (1906–1908) used blue to create a fantastic and exotic atmosphere. In Germany, Wassily Kandinsky and other Russian émigrés formed the art group called Der Blaue Reiter (The Blue Rider), and used blue to symbolise spirituality and eternity. Henri Matisse used intense blues to express the emotions he wanted viewers to feel. Matisse wrote, "A certain blue penetrates your soul."

In the art of the second half of the 20th century, painters of the abstract expressionist movement began to use blue and other colours in pure form, without any attempt to represent anything, to inspire ideas and emotions. Painter Mark Rothko observed that colour was "only an instrument;" his interest was "in expressing human emotions tragedy, ecstasy, doom, and so on."

In fashion blue, particularly dark blue, was seen as a colour which was serious but not grim. In the mid-20th century, blue passed black as the most common colour of men's business suits, the costume usually worn by political and business leaders. Public opinion polls in the United States and Europe showed that blue was the favourite colour of over fifty per cent of respondents. Green was far behind with twenty per cent, while white and red received about eight per cent each.

In 1873, a German immigrant in San Francisco, Levi Strauss, invented a sturdy kind of work trousers, made of denim fabric and coloured with indigo dye, called blue jeans. In 1935, they were raised to the level of high fashion by Vogue magazine. Beginning in the 1950s, they became an essential part of uniform of young people in the United States, Europe, and around the world.

Blue was also seen as a colour which was authoritative without being threatening. Following the Second World War, blue was adopted as the colour of important international organisations, including the United Nations, the Council of Europe, UNESCO, the European Union, and NATO. United Nations peacekeepers wear blue helmets to stress their peacekeeping role. Blue is used by the NATO Military Symbols for Land Based Systems to denote friendly forces, hence the term "blue on blue" for friendly fire, and Blue Force Tracking for location of friendly units. The People's Liberation Army of China (formerly known as the "Red Army") uses the term "Blue Army" to refer to hostile forces during exercises.

The 20th century saw the invention of new ways of creating blue, such as chemiluminescence, making blue light through a chemical reaction.

In the 20th century, it also became possible for one to own a shade of blue. The French artist Yves Klein, with the help of a French paint dealer, created a specific blue called International Klein blue, which he patented. It was made of ultramarine combined with a resin called Rhodopa, which gave it a particularly brilliant colour. The baseball team the Los Angeles Dodgers developed its own blue, called Dodger blue, and several American universities invented new blues for their colours.

With the dawn of the World Wide Web, blue has become the standard colour for hyperlinks in graphic browsers (in most browsers, links turn purple after visiting their target), to make their presence within text obvious to readers.

During his Blue Period, Pablo Picasso used blue as the colour of melancholy, as in The Old Guitarist.

The Blue Rider (1903), by Wassily Kandinsky, For Kandinsky, blue was the colour of spirituality: the darker the blue, the more it awakened human desire for the eternal.

The Russian avant-garde painter Pavel Kuznetsov and his group, the Blue Rose, used blue to symbolise fantasy and exoticism. This is In the Steppe – Mirage (1911).

Blue jeans, made of denim coloured with indigo dye, patented by Levi Strauss in 1873, became an essential part of the wardrobe of young people beginning in the 1950s.

Vivid blues can be created by chemical reactions, called chemiluminescence. This is luminol, a chemical used in crime scene investigations. Luminol glows blue when it contacts even a tiny trace of blood.

Blue neon lighting, first used in commercial advertising, is now used in works of art. This is Zwei Pferde für Münster (Two horses for Münster), a neon sculpture by Stephan Huber (2002), in Munster, Germany.

The Story Bridge in Brisbane, Australia illuminated in blue light for ovarian cancer awareness.

A man of the Tuareg people of North Africa wears a tagelmust or turban dyed with indigo. The indigo stains their skin blue; they were known by early visitors as "the blue men" of the desert.

Various shades of blue are used as the national colours for many nations.

A painting by William Hogarth from 1854 shows a polling station with the blue flag of the Tory party and the orange flag of the Whigs.

The blue necktie of former British Prime Minister David Cameron represented his Conservative Party.

Blue stripes on a traditional Jewish tallit. The blue stripes are also featured in the flag of Israel.

Vishnu, the supreme god of Hinduism, is often portrayed as being blue, or more precisely having skin the colour of rain-filled clouds.

In Catholicism, blue became the traditional colour of the robes of the Virgin Mary in the 13th century.

The Bhaisajyaguru, or "Medicine Master of Lapis Lazuli Light", is the Buddha of healing and medicine in Mahayana Buddhism. He traditionally holds a lapis lazuli jar of medicine.

In the Islamic World, blue and turquoise tile traditionally decorates the facades and exteriors of mosques and other religious buildings. This mosque is in Isfahan, Iran.

Blue was first used as a gender signifier just prior to World War I (for either girls or boys), and first established as a male gender signifier in the 1940s.

Madame Pompadour, the mistress of King Louis XV of France, wore blue myosotis, or forget-me-not flowers in her hair and on her gowns as a symbol of faithfulness to the king.

Many sporting teams make blue their official colour, or use it as detail on kit of a different colour. In addition, the colour is present on the logos of many sports associations. Along with red, blue is the most commonly used non-white colours for teams.

In international association football, blue is a common colour on kits, as a majority of nations wear the colours of their national flag. A notable exception to this link is four-time FIFA World Cup winners Italy, who wear a blue kit based on the Azzuro Savoia (Savoy blue) of the royal House of Savoy which unified the Italian states, despite the Italian national flag being green, white and red. The team themselves are known as Gli Azzurri (the Azures). Another World Cup winning nation with a blue shirt is France, who are known as Les Bleus (the Blues). Two neighbouring countries with two World Cup victories each, Argentina and Uruguay wear a light blue shirt, the former with white stripes. Uruguay are known as the La Celeste, Spanish for 'the sky blue one', while Argentina are known as Los Albicelestes, Spanish for 'the sky blue and whites'.

Blue features on the logo of football's governing body FIFA, as well as featuring highly in the design of their website. The European governing body of football, UEFA, uses two tones of blue to create a map of Europe in the centre of their logo. The Asian Football Confederation, Oceania Football Confederation and CONCACAF (the governing body of football in North and Central America and the Caribbean) use blue text on their logos.

In Major League Baseball, the premier baseball league in the United States and Canada, blue is one of the three colours, along with white and red, on the league's official logo. A team from Toronto, Ontario are nicknamed the Blue Jays. Sixteen other teams either regularly feature blue hats or utilise the colour in their uniforms.

The National Basketball Association, the premier basketball league in the United States and Canada, also has blue as one of the colours on their logo, along with red and white also, as did its female equivalent, the WNBA, until March 28, 2011, when the latter adopted an orange and white logo. Former NBA player Theodore Edwards was nicknamed "Blue". Fifteen NBA teams feature the colour in their uniforms.

The National Football League, the premier American football league in the United States, also uses blue as one of three colours, along with white and red, on their official logo. Thirteen NFL teams prominently feature the colour.

The National Hockey League, the premier Ice hockey league in Canada and the United States, uses blue on its official logo. Ten teams prominently feature the colour, with two teams (Columbus Blue Jackets and St. Louis Blues) featuring the colour in their nicknames. The team in St. Louis is primarily nicknamed after the eponymous music genre.

The Italian national football team wear blue in honour of the royal House of Savoy which unified the country.

The Indian national cricket team wears blue uniform during One day international matches, as such the team is also referred to as "Men in Blue".

Chefchaouen, a small town in northern Morocco, is most famous for their vivid blue walls in its “old town” sector. The maze-like medina sector features a fusion of Spanish and Moorish architecture. The brilliantly blue walls, however, seem to be unique to Chefchaouen. They are said to have been introduced to the town by Jewish refugees in 1930, who considered blue to symbolize the sky and heaven.
