Primary color
sets of colors that can be combined to make a useful range of colors / From Wikipedia, the free encyclopedia
Primary colors (or primary colours in Commonwealth English) are sets of colors that can be mixed to make a useful range of colors. The primary colors are those which cannot be made by mixing other colors in a given color space.
For an additive color model, as in overlapping projected lights or in television and computer screens, the primary colors are red, green, and blue.
For a subtractive color model, as in mixing of pigments or dyes for printing, the CMY(K) set of primaries is often used. In this system the primary colors are cyan, magenta,and yellow.[1] Other sets include the RYB system of red, yellow, blue, especially used by artists.[2]
