A secondary color is a color made by mixing two primary colors in a given color space. Examples include the following:

[edit] Light (RGB)
Main article: RGB color model
| red | (●) | + | green | (●) | = | yellow | (●) | ||
| green | (●) | + | blue | (●) | = | cyan | (●) | ||
| blue | (●) | + | red | (●) | = | magenta | (●) | ||

[edit] Pigment (CMY)
Main article: CMYK color model
| cyan | (●) | + | magenta | (●) | = | blue | (●) | ||
| magenta | (●) | + | yellow | (●) | = | red | (●) | ||
| yellow | (●) | + | cyan | (●) | = | green | (●) | ||
This is often referred to as CMYK where K stands for Key (usually black). In theory, solid overlapping layers of C, M, and Y ink produce black. In reality the outcome is dirty brown unless mixed exactly evenly so the black ink replaces the other three layers. See under color removal.
[edit] Traditional painting (RYB)
Main article: RYB color model
| red | (●) | + | yellow | (●) | = | orange | (●) | ||
| yellow | (●) | + | blue | (●) | = | green | (●) | ||
| blue | (●) | + | red | (●) | = | violet | (●) | ||
RYB uses pigments, similar to CMY, which combine subtractively by absorbing light. Thus, combining colors using the RYB color system will result in a darker color.
