Violet is the color of light at the short wavelength end of the visible spectrum. It is one of the seven colors that Isaac Newton labeled when dividing the spectrum of visible light in 1672. Violet light has a wavelength between approximately 380 and 435 nanometers. [2] The color's name is derived from the Viola genus of flowers. [3] [4]

In the RGB color model used in computer and television screens, violet is produced by mixing red and blue light, with more blue than red. In the RYB color model historically used by painters, violet is created with a combination of red and blue pigments and is located between blue and purple on the color wheel. In the CMYK color model used in printing, violet is created with a combination of magenta and cyan pigments, with more magenta than cyan. On the RGB/CMY(K) color wheel, violet is located between blue and magenta.

Violet is closely associated with purple. In optics, violet is a spectral color (referring to the color of different single wavelengths of light), whereas purple is the color of various combinations of red and blue (or violet) light, [5] [6] some of which humans perceive as similar to violet. In common usage, both terms are used to refer to a variety of colors between blue and red in hue. [7] [8] [9]

Violet has a long history of association with royalty, originally because Tyrian purple dye was extremely expensive in antiquity. [10] The emperors of Rome wore purple togas, as did the Byzantine emperors. During the Middle Ages, violet was worn by bishops and university professors and was often used in art as the color of the robes of the Virgin Mary. [11] In Chinese painting, the color violet represents the "unity transcending the duality of Yin and yang" and "the ultimate harmony of the universe". [12] In New Age thinking, purple and/or violet is associated with the crown chakra. [13] One European study suggests that violet is the color people most often associate with extravagance, individualism, vanity and ambiguity. [14]

The word violet as a color name derives from the Middle English and Old French violete, in turn from the Latin viola, the name of the violet flower. [3] [4] The first recorded use as a color name in English was in 1370. [15]

Relationship to purple

Violet is closely associated with purple. In optics, violet is a spectral color: It refers to the color of any different single wavelength of light on the short wavelength end of the visible spectrum (between approximately 380 and 435 nanometers), [16] [17] whereas purple is the color of various combinations of red, blue and violet light, [5] [6] some of which some humans perceive as similar to violet. In common usage, both terms are used to refer to a variety of colors between blue and red in hue. [7] [8] [9] Historically, violet has tended to be used for bluer hues and purple for redder hues. [7] [18] [19] In the traditional color wheel used by painters, violet and purple are both placed between red and blue, with violet being closer to blue. [20]

In science

Optics

Linear visible spectrum.svg

Violet is at one end of the spectrum of visible light, between blue light, which has a longer wavelength, and ultraviolet light, which has a shorter wavelength and is not visible to humans. Violet wavelengths are between approximately 380 and 435 nanometers. Violet objects often appear dark, because human vision becomes less sensitive at wavelengths this short.[ citation needed ] The reason why to (typical trichromat) humans violet light appears slightly reddish compared to spectral blue (despite spectral red being at the other end of the visible spectrum) is, according to the opponent process hypothesis of color vision, that the S-cone type (i.e. the one most sensitive to short wavelengths) contributes some red to the red-versus-green opponent channel (which at the longer blue wavelengths gets counteracted by the M-cone type). [21] Computer and television screens, using the RGB color model, cannot produce actual violet light and instead mimic it by combining blue light at high intensity with red light at less intensity.

Violet objects are normally composed-light violet. Objects reflecting spectral violet appear very dark, because human vision is relatively insensitive to those wavelengths.[ citation needed ] Monochromatic lamps emitting spectral-violet wavelengths can be roughly approximated by the color named electric violet, which is a composed-light violet producing a similar effect to the human eye.[ citation needed ]

Chemistry – pigments and dyes

The earliest violet pigments used by humans, found in prehistoric cave paintings, were made from the minerals manganese and hematite. Manganese is still used today by the Aranda people, a group of indigenous Australians, as a traditional pigment for coloring the skin during rituals. It is also used by the Hopi Indians of Arizona to color ritual objects.

The most famous violet-purple dye in the ancient world was Tyrian purple, made from a type of sea snail called the murex, found around the Mediterranean.

In western Polynesia, residents of the islands made a violet dye similar to Tyrian purple from the sea urchin. In Central America, the inhabitants made a dye from a different sea snail, the purpura, found on the coasts of Costa Rica and Nicaragua. The Mayans used this color to dye fabric for religious ceremonies, and the Aztecs used it for paintings of ideograms, where it symbolized royalty. [22]

During the Middle Ages, most artists made purple or violet on their paintings by combining red and blue pigments; usually blue azurite or lapis-lazuli with red ochre, cinnabar or minium. They also combined lake colors by mixing dye with powder; woad or indigo dye for blue and cochineal dye for red. [22]

Orcein, or purple moss, was another common violet dye. It was known to the ancient Greeks and Hebrews, was made from a Mediterranean lichen called archil or dyer's moss (Roccella tinctoria), combined with an ammoniac, usually urine. Orcein began to achieve popularity again in the 19th century, when violet and purple became the color of demi-mourning, worn after a widow or widower had worn black for a certain time, before he or she returned to wearing ordinary colors. [23]

In the 18th century, chemists in England, France and Germany began to create the first synthetic dyes. Two synthetic purple dyes were invented at about the same time. Cudbear is a dye extracted from orchil lichens that can be used to dye wool and silk, without the use of mordant. Cudbear was developed by Cuthbert Gordon of Scotland: production began in 1758, The lichen is first boiled in a solution of ammonium carbonate. The mixture is then cooled and ammonia is added and the mixture is kept damp for 3–4 weeks. Then the lichen is dried and ground to powder. The manufacture details were carefully protected, with a ten-foot high wall built around the manufacturing facility, and staff consisting of Highlanders sworn to secrecy.

French purple was developed in France at about the same time. The lichen is extracted by urine or ammonia. Then the extract is acidified, the dissolved dye precipitates and is washed. Then it is dissolved in ammonia again, the solution is heated in air until it becomes purple, then it is precipitated with calcium chloride; the resulting dye was more solid and stable than other purples.

Cobalt violet is a synthetic pigment that was invented in the second half of the 19th century, and is made by a similar process as cobalt blue, cerulean blue and cobalt green. It is the violet pigment most commonly used today by artists, along with manganese violet.

Mauveine , also known as aniline purple and Perkin's mauve , was the first synthetic organic chemical dye, [24] [25] discovered serendipitously during an attempt to make quinine in 1856. Its chemical name is 3-amino-2,±9-dimethyl-5-phenyl-7-(p-tolylamino) phenazinium acetate.

In the 1950s, a new family of violet synthetic organic pigments called quinacridones came onto the market. They had originally been discovered in 1896, synthesized in 1936 and manufactured in the 1950s. The colors in the group range from deep red to violet in color, and have the molecular formula C20H12N2O2. They have strong resistance to sunlight and washing, and are used in oil paints, watercolors and acrylics, as well as in automobile coatings and other industrial coatings.

In history and art

Prehistory and antiquity

Violet is one of the oldest colors used by humans. Traces of very dark violet, made by grinding the mineral manganese, mixed with water or animal fat and then brushed on the cave wall or applied with the fingers, are found in the prehistoric cave art in Pech Merle, in France, dating back about 25,000 years. It has also been found in the cave of Altamira and Lascaux. [26] It was sometimes used as an alternative to black charcoal. Sticks of manganese, used for drawing, have been found at sites occupied by Neanderthals in France and Israel. From the grinding tools at various sites, it appears it may also have been used to color the body and to decorate animal skins.

More recently, the earliest dates on cave paintings have been pushed back farther than 35,000 years. Hand paintings on rock walls in Australia may be even older, dating back as far as 50,000 years.

Berries of the genus rubus, such as blackberries, were a common source of dyes in antiquity. The ancient Egyptians made a kind of violet dye by combining the juice of the mulberry with crushed green grapes. The Roman historian Pliny the Elder reported that the Gauls used a violet dye made from bilberry to color the clothing of slaves. These dyes made a satisfactory purple, but it faded quickly in sunlight and when washed. [27]

Middle Ages and Renaissance

Violet and purple retained their status as the color of emperors and princes of the church throughout the long rule of the Byzantine Empire.

While violet was worn less frequently by Medieval and Renaissance kings and princes, it was worn by the professors of many of Europe's new universities. Their robes were modeled after those of the clergy, and they often wore square violet caps and violet robes, or black robes with violet trim.

Violet also played an important part in the religious paintings of the Renaissance. Angels and the Virgin Mary were often portrayed wearing violet robes. The 15th-century Florentine painter Cennino Cennini advised artists: "If you want to make a lovely violet colour, take fine lacca, ultramarine blue (the same amount of the one as of the other)..." For fresco painters, he advised a less-expensive version, made of a mixture of blue indigo and red hematite. [28]

18th and 19th centuries

In the 18th century, purple was a color worn by royalty, aristocrats and other wealthy people. Good-quality purple fabric was too expensive for ordinary people.

The first cobalt violet, the intensely red-violet cobalt arsenate, was highly toxic. Although it persisted in some paint lines into the 20th century, it was displaced by less toxic cobalt compounds such as cobalt phosphate. Cobalt violet appeared in the second half of the 19th century, broadening the palette of artists with its range of purple colors. Cobalt violet was used by Paul Signac (1863–1935), Claude Monet (1840–1926) and Georges Seurat (1859–1891). [29] Today, cobalt ammonium phosphate, cobalt lithium phosphate and cobalt phosphate are available for use by artists. Cobalt ammonium phosphate is the most reddish of the three. Cobalt phosphate is available in two varieties — a deep less saturated blueish type and a lighter and brighter somewhat more reddish type. Cobalt lithium phosphate is a saturated lighter-valued bluish violet. A color similar to cobalt ammonium phosphate, cobalt magnesium borate, was introduced in the later 20th century but was not deemed sufficiently lightfast for artistic use. Cobalt violet is the only truly lightfast purple pigment with relatively strong color saturation. All other light-stable purple pigments are dull by comparison. The high price of the pigment and the toxicity of cobalt have limited its use.

In the 1860s, the popularity of using violet colors suddenly rose among painters and other artists. [7] For example, Vincent van Gogh (1853–1890) was an avid student of color theory. He used violet in many of his paintings of the 1880s, including his paintings of irises and the swirling and mysterious skies of his starry night paintings, and often combined it with its complementary color, yellow. In his painting of his bedroom in Arles (1888), he used several sets of complementary colors; violet and yellow, red and green and orange and blue. In a letter about the painting to his brother Theo, he wrote, "The color here...should be suggestive of sleep and repose in general....The walls are a pale violet. The floor is of red tiles. The wood of the bed and the chairs are fresh butter yellow, the sheet and the pillows light lemon green. The bedspread bright scarlet. The window green. The bed table orange. The bowl blue. The doors lilac....The painting should rest the head or the imagination." [30]

In 1856, a young British chemist named William Henry Perkin was trying to make a synthetic quinine. His experiments produced instead an unexpected residue, which turned out to be the first synthetic aniline dye, a deep purple [7] color called mauveine, or abbreviated simply to mauve (the dye being named after the lighter color of the mallow [mauve] flower). Used to dye clothes, it became extremely fashionable among the nobility and upper classes in Europe, particularly after Queen Victoria wore a silk gown dyed with mauveine to the Royal Exhibition of 1862. Prior to Perkin's discovery, mauve was a color which only the aristocracy and rich could afford to wear. Perkin developed an industrial process, built a factory, and produced the dye by the ton so almost anyone could wear mauve. It was the first of a series of modern industrial dyes which completely transformed both the chemical industry and fashion. [31]

Violet or purple neckties became popular at the end of the first decade of the 21st century, particularly among political and business leaders.[ citation needed ]

In culture

Popularity

In a European survey, three percent of respondents said violet is their favorite color, ranking it behind blue, green, red, black and yellow (in that order), and tied with orange. Ten percent called it their least favorite color; brown, pink and gray were more unpopular. [14]

Royalty and luxury

Because of its status as the color of Roman emperors, monarchs and princes, purple and violet are often associated with luxury. Certain luxury goods, such as watches and jewelry, are often placed in boxes lined with violet velvet, since violet is the complementary color of yellow and shows gold to best advantage.

Vanity, extravagance and individualism

While violet is the color of humility in the symbolism of the Catholic Church, it has exactly the opposite meaning in general society. A European poll in 2000 showed it was the color most commonly associated with vanity. [32] As a color that rarely exists in nature and so attracts attention, it is seen as a color of individualism and extravagance.

In Japan, violet was a popular color introduced into dress during the Heian period (794–1185). The dye was made from the root of the alkanet plant (Anchusa officinalis), known as murasaki in Japanese. At about the same time, Japanese painters began to use a pigment made from the same plant. [33]

New Age

The "New Age Prophetess", Alice Bailey, in her system called the Seven Rays which classifies humans into seven different metaphysical psychological types, the "seventh ray" of "Ceremonial Order" is represented by the color violet. People who have this metaphysical psychological type are said to be "on the Violet Ray". [34]

In the Ascended Master Teachings, the color violet is used to represent the Ascended Master St. Germain. [35]

The Invocation of the Violet Flame is a system of meditation practice used in the "I AM" Activity and by the Church Universal and Triumphant (both Ascended Master Teaching religions).

Religion

In the Roman Catholic church, violet is worn by bishops and archbishops, red by cardinals and white by the Pope. Ordinary priests wear black. As in many other Western churches, violet is the liturgical color of Advent and Lent, which respectively celebrate the expectant waiting and preparation for the celebration of the Crucifixion of Jesus and the time for penance and/or mourning.

A stained glass window installed in the early 1920s in the Cathedral of Our Lady of the Angels in Los Angeles depicts God the Father wearing a violet robe. [36]

After the Vatican II Council, which modified many of the rules of the Catholic church, priests began to wear violet robes when celebrating masses for the dead. Black was no longer used, since it was the color of mourning outside the church and deemed inappropriate in a religious ceremony. [37]

In Hinduism, violet is used to symbolically represent the seventh, crown chakra (Sahasrara). [38]

Politics

The Susan B. Anthony stamp (1936), was the reddish tone of purple sometimes known as red-violet since violet was a color that represented the Women's Suffrage movement.

In the early 20th century, violet, white and gold were the colors of the women's suffrage movement in the United States, seeking the right to vote for women. The colors were said to represent liberty and dignity. [39] [40] For this reason, the postage stamp issued in 1936 to honor Susan B. Anthony, a prominent leader of the suffrage movement in the United States, was colored the reddish tone of violet sometimes known as red-violet.

In 1908, Emmeline Pethick-Lawrence, co-editor of the Women's Social and Political Union (WSPU) newspaper, designed the color scheme for the suffragette movement in Britain and Ireland, with violet for loyalty and dignity, white for purity and green for hope. [41] [42] [43]

The pan-European movement Volt Europa and its national subsidiary parties use violet in their uniforms. [44]

A small New Age political party in Germany with about 1,150 members is called The Violet Party. It believes in direct democracy, a guaranteed minimum income and politics based on spirituality. It was founded in Dortmund in 2001. [45]

Lesbianism

Violet flowers and their color became symbolically associated with lesbian love. [46] It was used as a special code by lesbians and bisexual women for self-identification and also to communicate support for the sexual preference. [47] [48] This connection originates from the poet Sappho and fragments of her poems. In one poem, she describes a lost love wearing a garland of "violet tiaras, braided rosebuds, dill and crocus twined around" her neck. [49] In another fragment, she recalls her lover as having "put around yourself [many wreaths] of violets and roses." [50] [51]

The labrys lesbian flag, created in 1999 by graphic designer Sean Campbell, [52] [53] features a labrys superimposed on the inverted black triangle set against a violet background. [54] [55]

<span class="mw-page-title-main">Black</span> Darkest color due to absence or absorption of light

Black is a color that results from the absence or complete absorption of visible light. It is an achromatic color, without hue, like white and grey. It is often used symbolically or figuratively to represent darkness. Black and white have often been used to describe opposites such as good and evil, the Dark Ages versus Age of Enlightenment, and night versus day. Since the Middle Ages, black has been the symbolic color of solemnity and authority, and for this reason it is still commonly worn by judges and magistrates.

<span class="mw-page-title-main">Blue</span> Colour between violet and cyan on the visible spectrum of light

Blue is one of the three primary colours in the RYB colour model, as well as in the RGB (additive) colour model. It lies between violet and cyan on the spectrum of visible light. The term blue generally describes colours perceived by humans observing light with a dominant wavelength that's 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 the Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective.

<span class="mw-page-title-main">Green</span> Additive primary color visible between cyan and yellow

Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495–570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content.

<span class="mw-page-title-main">Red</span> Primary color

Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and a secondary color in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy.

<span class="mw-page-title-main">Yellow</span> Color between orange and green on the visible spectrum of light

Yellow is the color between green and orange on the spectrum of light. It is evoked by light with a dominant wavelength of roughly 575–585 nm. It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity. Carotenoids give the characteristic yellow color to autumn leaves, corn, canaries, daffodils, and lemons, as well as egg yolks, buttercups, and bananas. They absorb light energy and protect plants from photo damage in some cases. Sunlight has a slight yellowish hue when the Sun is near the horizon, due to atmospheric scattering of shorter wavelengths.

<span class="mw-page-title-main">Purple</span> Range of colors with the hues between blue and red

Purple is a color similar in appearance to violet light. In the RYB color model historically used in the arts, purple is a secondary color created by combining red and blue pigments. In the CMYK color model used in modern printing, purple is made by combining magenta pigment with either cyan pigment, black pigment, or both. In the RGB color model used in computer and television screens, purple is created by mixing red and blue light in order to create colors that appear similar to violet light.

<span class="mw-page-title-main">Brown</span> Color

Brown is a color. It can be considered a composite color, but it is mainly a darker shade of orange. In the CMYK color model used in printing and painting, brown is usually made by combining the colors orange and black.

<span class="mw-page-title-main">Magenta</span> Color

Magenta is a purplish-red color. On color wheels of the RGB (additive) and CMY (subtractive) color models, it is located precisely midway between blue and red. It is one of the four colors of ink used in color printing by an inkjet printer, along with yellow, cyan, and black to make all the other colors. The tone of magenta used in printing, printer's magenta, is redder than the magenta of the RGB (additive) model, the former being closer to rose.

<span class="mw-page-title-main">Pigment</span> Colored material

A pigment is a powder used to add color or change visual appearance. Pigments are completely or nearly insoluble and chemically unreactive in water or another medium; in contrast, dyes are colored substances which are soluble or go into solution at some stage in their use. Dyes are often organic compounds whereas pigments are often inorganic. Pigments of prehistoric and historic value include ochre, charcoal, and lapis lazuli.

<span class="mw-page-title-main">Orange (colour)</span> Colour located between red and yellow

Orange is the colour between yellow and red on the spectrum of visible light. The human eyes perceive orange when observing light with a dominant wavelength between roughly 585 and 620 nanometres. In traditional colour theory, it is a secondary colour of pigments, produced by mixing yellow and red. In the RGB colour model, it is a tertiary colour. It is named after the fruit of the same name.

<span class="mw-page-title-main">Complementary colors</span> Pairs of colors losing hue when combined

Complementary colors are pairs of colors which, when combined or mixed, cancel each other out by producing a grayscale color like white or black. When placed next to each other, they create the strongest contrast for those two colors. Complementary colors may also be called "opposite colors".

<span class="mw-page-title-main">Subtractive color</span> Light passing through successive filters

Subtractive color or subtractive color mixing predicts the spectral power distribution of light after it passes through successive layers of partially absorbing media. This idealized model is the essential principle of how dyes and pigments are used in color printing and photography, where the perception of color is elicited after white light passes through microscopic "stacks" of partially absorbing media allowing some wavelengths of light to reach the eye and not others, and also in painting, whether the colors are mixed or applied in successive layers.

<span class="mw-page-title-main">Grey</span> Intermediate color between black and white

Grey or gray is an intermediate color between black and white. It is a neutral or achromatic color, meaning that it has no chroma and therefore no hue. It is the color of a cloud-covered sky, of ash, and of lead.

White is the lightest color and is achromatic. It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide.

In the 19th century, the colour was often used for military uniforms and fashion.

<span class="mw-page-title-main">Red pigments</span> Materials used to make red colors in painting

Red pigments are materials, usually made from minerals, used to create the red colors in painting and other arts. The color of red and other pigments is determined by the way it absorbs certain parts of the spectrum of visible light and reflects the others. The brilliant opaque red of vermillion, for example, results because vermillion reflects the major part of red light, but absorbs the blue, green and yellow parts of white light.

<span class="mw-page-title-main">Green pigments</span> Substances reflecting light between 475-590 nm

Green pigments are the materials used to create the green colors seen in painting and the other arts. Most come from minerals, particularly those containing compounds of copper. Green pigments reflect the green portions of the spectrum of visible light, and absorb the others. Important green pigments in art history include Malachite and Verdigris, found in tomb paintings in Ancient Egypt, and the Green earth pigments popular in the Middle Ages. More recent greens, such as Cobalt Green, are largely synthetic, made in laboratories and factories.
