A tertiary color is a color made by mixing one primary color with one secondary color, in a given color space such as RGB[1] (more modern) or RYB[2] (traditional).
Tertiary colors have specific names, one set of names for the RGB color wheel and a different set of names and colors for the RYB color wheel. These names are shown below.
Brown and grey colors can be made by mixing complementary colors.

[edit] RGB or CMY primary, secondary, and tertiary 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.
| cyan | (●) | + | blue | (●) | = | azure | (●) |
| blue | (●) | + | magenta | (●) | = | violet | (●) |
| magenta | (●) | + | red | (●) | = | rose | (●) |
| red | (●) | + | yellow | (●) | = | orange | (●) |
| yellow | (●) | + | green | (●) | = | chartreuse | (●) |
| green | (●) | + | cyan | (●) | = | spring green | (●) |
[edit] Traditional painting and interior design (RYB)
The primary colors in an RYB color wheel are red, yellow, and blue. The secondary colors in an RYB color wheel are made by combining the primary colors--orange, green, and violet.
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.[3][4]
| red | (●) | + | orange | (●) | = | red-orange | (●) |
| orange | (●) | + | yellow | (●) | = | yellow-orange[5] | (●) |
| yellow | (●) | + | green | (●) | = | yellow-green | (●) |
| green | (●) | + | blue | (●) | = | blue-green[5] | (●) |
| blue | (●) | + | violet | (●) | = | blue-violet | (●) |
| violet | (●) | + | red | (●) | = | red-violet | (●) |
[edit] Comparison of RGB and RYB color wheels
Unlike the RGB color wheel, the RYB color wheel has no scientific basis. The RYB color wheel was invented centuries before the 1890s, when it was found by experiment that magenta, yellow, and cyan are the primary colors of pigment, not red, yellow, and blue.
The modern RGB color wheel has largely replaced the traditional old-fashioned RYB color wheel because it is possible to display much brighter and more saturated colors using the primary and secondary colors of the RGB color wheel. In the terminology of color theory, RGB color space has a much larger color gamut than RYB color space.
