Mixture of RYB primary colors

RYB (an abbreviation of red-yellow-blue) is a historical set of subtractive primary colors. It is primarily used in art and art education, particularly painting.

Color Wheel

Standard RYB Color Wheel

RYB make up the primary color triad in a standard color wheel. The secondary colors VOG (violet-orange-green) also make up another triad. Triads are formed by 3 equidistant colors on a particular color wheel. Other common color wheels^{[citation needed]} include the light model and the print model.

History

The RYB primary colors became the foundation of 18th century theories of color vision, as the fundamental sensory qualities that are blended in the perception of all physical colors and equally in the physical mixture of pigments or dyes. These theories were enhanced by 18th-century investigations of a variety of purely psychological color effects, in particular the contrast between "complementary" or opposing hues that are produced by color afterimages and in the contrasting shadows in colored light. These ideas and many personal color observations were summarized in two founding documents in color theory: the Theory of Colors (1810) by the German poet and government minister Johann Wolfgang von Goethe, and The Law of Simultaneous Color Contrast (1839) by the French industrial chemist Michel-Eugène Chevreul. Theory of Colours (Zur Farbenlehre in German) was a work published by Johann Wolfgang von Goethe in 1810. ... “Goethe” redirects here. ... Michel Eugène Chevreul (August 31, 1786 – April 9, 1889) was an important French chemist whose work with fatty acids led to early applications in the fields of art and science. ...

Subsequently, German and English scientists established in the late 19th century that color perception is best described in terms of a different set of primary colors -- red, green and blue (RGB) -- modeled through the additive, rather than subtractive, mixture of three monochromatic lights. RGB redirects here. ... Additive color mixing: adding red to green yields yellow; adding yellow to blue yields white. ...

Painters have long used more than three RYB primary colors in their palettes—and at one point considered red, yellow, blue, and green to be the four primaries^[1]. Red, yellow, blue, and green are still widely considered the four psychological primary colors^[2], though red, yellow, blue and are sometimes listed as the three psychological primaries ^[3], with black and white occasionally added as a fourth and fifth ^[4].

Limitations and Eccentricities

In the RGB color space the colors are added, thus you start with levels of dark colors which are added to produce lighter colors. RYB uses pigments, which are not added, and thus combining colors using the RYB color system will result in a darker color. Because of this it is impossible to create magenta, because its value would normally be the combined value of Red and Blue, but combining them using pigments creates a darker color (namely purple or violet). Because of this any color in between red and blue must be darker than red and blue, and any color between yellow and red or yellow and blue must be darker than yellow. An RGB color space is any additive color space based on the RGB color model. ... Magenta is a color made up of equal parts of red and blue light. ...
