Tertiary color

A tertiary color is a color made by mixing full saturation of one primary color with half saturation of another primary color and none of a third primary color, in a given color space such as RGB,CMYK (more modern) or RYB (traditional).

Tertiary colors have specific names, one set of names for the RGB color wheel and a different set for the RYB color wheel. These names are shown below.

Brown and grey colors can be made by mixing complementary colors.

The primary colors in an RGB color wheel are red, green, and blue, because these are the three additive colors—the primary colors of light. The secondary colors in an RGB color wheel are cyan, magenta, and yellow because these are the three subtractive colors—the primary colors of pigment.

The tertiary color names used in the descriptions of RGB (or equivalently CMYK) systems are shown below.

The primary colors in an RYB color wheel are red, yellow, and blue. The secondary colors — orange, green, and purple — are made by combining the primary colors

In the red–yellow–blue system as used in traditional painting and interior design, tertiary colors are typically named by combining the names of the adjacent primary and secondary.

The terms for the RYB tertiary colors are not set. For the six RYB hues intermediate between the RYB primary and secondary colors, the names amber/marigold (yellow–orange), vermilion/cinnabar (red–orange), magenta (red–purple), violet (blue–purple), teal/aqua (blue-green), and chartreuse/lime green (yellow–green) are commonly found. The names for the twelve quaternary colors are more variable, if they exist at all, though indigo and scarlet are standard for blue–violet and red–vermilion.
