are pairs of colors which, when combined or mixed, cancel each other out (lose hue) by producing a grayscale colour similar white or black.[i]

When placed adjacent to each other, they create the strongest contrast for those two colors. Complementary colors may also be called “contrary colors”.
Which pairs of colors are considered complementary depends on the color theory one uses:
- Modern color theory uses either the RGB additive colour model or the CMY subtractive color model, and in these, the complementary pairs are
- In the traditional RYB color model, the complementary colour pairs are
- Opponent procedure theory suggests that the nigh contrasting color pairs are red–green, and bluish–yellow.
- The blackness-white color pair is mutual to all the in a higher place theories.
In different color models
Traditional colour model
The traditional color wheel model dates to the 18th century and is still used past many artists today. This model designates ruddy, yellow and blueish as main colors with the primary–secondary complementary pairs of blood-red–green, blueish-orange, and xanthous–majestic.[iii]
In this traditional scheme, a complementary color pair contains one primary color (yellow, blue or red) and a secondary color (green, royal or orange). The complement of whatever primary color tin be made by combining the ii other primary colors. For example, to achieve the complement of yellow (a primary color) one could combine carmine and blue. The result would exist purple, which appears directly across from yellow on the color bike.[four]
Continuing with the color cycle model, one could then combine xanthous and purple, which substantially means that all three principal colors would be present at one time. Since paints work by absorbing lite, having all three primaries together produces a black or gray color (come across subtractive color). In more recent painting manuals, the more precise subtractive primary colors are magenta, cyan and yellow.
Complementary colors can create some hit optical effects. The shadow of an object appears to contain some of the complementary colour of the object. For instance, the shadow of a red apple will appear to incorporate a little blueish-green. This effect is often copied by painters who want to create more luminous and realistic shadows. Likewise, if you stare at a square of color for a long menses of time (thirty seconds to a minute), and then expect at a white paper or wall, y’all will briefly see an afterimage of the foursquare in its complementary color.

Colors produced past light
The RGB color model, invented in the 19th century and fully developed in the 20th century, uses combinations of red, green, and blue calorie-free against a black groundwork to make the colors seen on a computer monitor or tv set screen. In the RGB model, the principal colors are red, green, and blue. The complementary master–secondary combinations are carmine–cyan, green–magenta, and blue–yellowish. In the RGB color model, the light of two complementary colors, such as red and cyan, combined at total intensity, will brand white calorie-free, since two complementary colors incorporate lite with the total range of the spectrum. If the light is not fully intense, the resulting low-cal will be greyness.
In some other colour models, such as the HSV color infinite, the neutral colors (white, grays, and blackness) lie along a central axis. Complementary colors (as divers in HSV) lie opposite each other on whatever horizontal cantankerous-section. For example, in the CIE 1931 colour space a color of a “ascendant” wavelength tin be mixed with an amount of the complementary wavelength to produce a neutral color (grey or white).

Color press, like painting, likewise uses subtractive colors, simply the complementary colors are different from those used in painting. As a result, the same logic applies every bit to colors produced by light. Colour printing uses the CMYK color model, making colors by overprinting cyan, magenta, yellowish, and blackness ink. In press the most common complementary colors are magenta–greenish, xanthous–blueish, and cyan–red. In terms of complementary/contrary colors, this model gives exactly the aforementioned result every bit using the RGB model. Blackness is added when needed to make the colors darker.
In theory and art
In color theory
The effect that colors accept upon each other had been noted since artifact. In his essay
On Colors, Aristotle observed that “when calorie-free falls upon another colour, then, every bit a effect of this new combination, it takes on another nuance of color”.[vii]
Saint Thomas Aquinas had written that majestic looked different next to white than it did next to blackness, and that golden looked more hit against blueish than it did against white; the Italian Renaissance builder and writer Leon Battista Alberti observed that in that location was harmony (coniugatio
in Latin, and
in Italian) betwixt certain colors, such every bit red–green and red–blue; and Leonardo da Vinci observed that the finest harmonies were those between colors exactly opposed (retto contrario), simply no one had a convincing scientific explanation why that was so until the 18th century.
In 1704, in his treatise on optics, Isaac Newton devised a circle showing a spectrum of seven colors. In this work and in an earlier work in 1672, he observed that sure colors effectually the circle were opposed to each other and provided the greatest contrast; he named blood-red and blue, yellow and violet, and green and “a purple close to ruby-red”.
In the following decades, scientists[
refined Newton’s color circle, eventually giving information technology twelve colors: the three chief colors (xanthous, blue, and red); three secondary colors (green, purple and orange), made past combining chief colors; and vi additional third colors, fabricated by combining the primary and secondary colors.[
In two reports read before the Royal Society (London) in 1794, the American-born British scientist Benjamin Thompson, Count Rumford (1753–1814), coined the term
to describe two colors that, when mixed, produce white. While conducting photometric experiments on factory lighting in Munich, Thompson noticed that an “imaginary” blue color was produced in the shadow of xanthous candlelight illuminated past skylight, an outcome that he reproduced in other colors by means of tinted glasses and pigmented surfaces. He theorized that “To every colour, without exception, whatsoever may be its hue or shade, or however it may be compounded, in that location is another in perfect harmony to information technology, which is its complement, and may be said to be its companion.” He besides suggested some possible practical uses of this discovery. “By experiments of this kind, which might easily be fabricated, ladies may cull ribbons for their gowns, or those who replenish rooms may adapt their colors upon principles of the most perfect harmony and of the purest taste. The advantages that painters might derive from a knowledge of these principles of the harmony of colors are as well obvious to require illustration.”
In the early on 19th century, scientists and philosophers across Europe began studying the nature and interaction of colors. The German poet Johann Wolfgang von Goethe presented his own theory in 1810, stating that the ii principal colors were those in the greatest opposition to each other, yellow and blue, representing light and darkness. He wrote that “Yellowish is a light which has been dampened by darkness; blue is a darkness weakened by light.”[x]
Out of the opposition of blue and yellow, through a process chosen “steigerung”, or “augmentation” a 3rd colour, red, was born.[
Goethe besides proposed several sets of complementary colors which “demanded” each other. According to Goethe, “yellow ‘demands’ violet; orange [demands] blue; imperial [demands] green; and vice versa”.
Goethe’s ideas were highly personal and often disagreed with other scientific research, only they were highly popular and influenced some of import artists, including J.M.W. Turner.
At about the same time that Goethe was publishing his theory, a British physicist, doc and Egyptologist, Thomas Young (1773–1829), showed by experiments that information technology was not necessary to utilize all the colors of spectrum to create white light; it could be done past combining the light of merely three colors; red, green, and blue. This discovery was the foundation of additive colors, and of the RGB color model.[thirteen]
He showed that it was possible to create magenta past combining red and blue light; to create xanthous past mixing red and green light; and to create cyan, or blue-green, by mixing green and blueish. He also found that it was possible to create most any other colour past modifying the intensity of these colors. This discovery led to the system used today to create colors on a reckoner or idiot box display. Young was also the showtime to propose that the retina of the eye contained nerve fibers which were sensitive to 3 different colors. This foreshadowed the modern understanding of color vision, in detail the finding that the eye does indeed have three color receptors which are sensitive to different wavelength ranges.
At about the same time equally Immature discovered condiment colors, some other British scientist, David Brewster (1781–1868), the inventor of the kaleidoscope, proposed a competing theory that the true primary colors were ruby-red, yellow, and blue, and that the true complementary pairs were red–green, blue–orange, and xanthous–purple. And so a German scientist, Hermann von Helmholtz, (1821–1894), resolved the contend past showing that colors formed past low-cal, additive colors, and those formed by pigments, subtractive colors, did in fact operate by different rules, and had different master and complementary colors.
Other scientists looked more closely at the use of complementary colors. In 1828, the French chemist Eugene Chevreul, making a report of the manufacture of Gobelin tapestries to make the colors brighter, demonstrated scientifically that “the arrangement of complementary colors is superior to any other harmony of contrasts”. His 1839 book on the subject,
De la loi du contraste simultané des couleurs et de l’assortiment des objets colorés, showing how complementary colors can be used in everything from textiles to gardens, was widely read in Germany, France and England, and made complementary colors a pop concept. The use of complementary colors was further publicized by the French art critic Charles Blanc in his book
Grammaire des arts et du dessin
(1867) and afterward past the American color theorist Ogden Rood in his book
(1879). These books were read with great enthusiasm by contemporary painters, especially Georges Seurat and Vincent van Gogh, who put the theories into practice in their paintings.
Newton’s colour circumvolve (1704) displayed seven colors. He alleged that colors contrary each other had the strongest dissimilarity and harmony.
A Boutet color circle from 1708 showed the traditional complementary colors; red and dark-green, yellowish and purple, and blue and orangish.
The color bike designed past Johann Wolfgang von Goethe (1810) was based on the thought that the primary colors yellow and bluish, representing light and darkness, were in opposition to each other.
In 1872, Claude Monet painted
Impression, Sunrise, a tiny orange sun and some orange lite reflected on the clouds and h2o in the heart of a hazy blue landscape. This painting, with its striking utilise of the complementary colors orangish and bluish, gave its proper noun to the impressionist movement. Monet was familiar with the science of complementary colors, and used them with enthusiasm. He wrote in 1888, “color makes its impact from contrasts rather than from its inherent qualities….the principal colors seem more brilliant when they are in contrast with their complementary colors”.
Orange and blueish became an important combination for all the impressionist painters. They all had studied the recent books on colour theory, and they knew that orange placed next to bluish made both colors much brighter. Auguste Renoir painted boats with stripes of chrome orangish pigment straight from the tube. Paul Cézanne used orange made of touches of yellow, red and ochre against a blueish groundwork.
Vincent van Gogh was specially known for using this technique; he created his own oranges with mixtures of yellow, ochre and red, and placed them side by side to slashes of sienna red and canteen-green, and beneath a heaven of turbulent blueish and violet. He also put an orange moon and stars in a cobalt blue sky. He wrote to his brother Theo of “searching for oppositions of blue with orangish, of red with green, of xanthous with purple, searching for cleaved colors and neutral colors to harmonize the brutality of extremes, trying to make the colors intense, and not a harmony of greys”.[eighteen]
Describing his painting,
The Dark Café, to his blood brother Theo in 1888, Van Gogh wrote: “I sought to limited with ruddy and greenish the terrible human passions. The hall is claret-ruddy and stake yellow, with a green billiard table in the center, and 4 lamps of lemon xanthous, with rays of orange and light-green. Everywhere information technology is a boxing and antithesis of the nigh unlike reds and greens.”
by Claude Monet (1872) featured a tiny but vivid orange sunday confronting a bluish groundwork. The painting gave its proper name to the Impressionist movement.
In this cocky-portrait (1889), Vincent van Gogh fabricated the almost of the contrast betwixt the orange of his hair and the blueish background.
by Vincent van Gogh (1889) features orange stars and an orange moon.
The Night Café
by Vincent van Gogh (1888) used red and green to express what van Gogh chosen “the terrible homo passions”.
When one stares at a single color (reddish for case) for a sustained period of time (roughly thirty seconds to a minute), then looks at a white surface, an afterimage of the complementary color (in this case cyan) volition appear. This is one of several aftereffects studied in the psychology of visual perception which are generally ascribed to fatigue in specific parts of the visual organization.
In the case higher up the photoreceptors for cherry-red light in the retina are fatigued, lessening their ability to ship the information to the encephalon. When white lite is viewed, the reddish portions of calorie-free incident upon the centre are not transmitted as efficiently as the other wavelengths (or colors), and the result is the illusion of viewing the complementary color since the image is now biased past loss of the colour, in this case blood-red. As the receptors are given fourth dimension to residue, the illusion vanishes. In the case of looking at the white lite, red light is nonetheless incident upon the eye (equally well every bit blue and light-green), still since the receptors for other light colors are also existence fatigued, the centre will reach an equilibrium.
The use of complementary colors is an important aspect of aesthetically pleasing art and graphic design. This also extends to other fields such as contrasting colors in logos and retail brandish. When placed adjacent to each other, complements make each other appear brighter.
Complementary colors also have more practical uses. Because orangish and blue are complementary colors, life rafts and life vests are traditionally orange, to provide the highest contrast and visibility when seen from ships or aircraft over the ocean.
Crimson and cyan glasses are used in the Anaglyph 3D system to produce 3D images on estimator screens.
Orange life rafts provide the highest contrast and visibility seen confronting bluish water.
Red and cyan spectacles are used for viewing Anaglyph 3D iii-dimensional images on the Net or in print.
