Primary colours
The primary colors are those which cannot be created by mixing other colors in a given color space. For subtractive combination of colors, as in mixing of pigments or dyes for printing, the CMYK set of primaries is often used. In this system the primary colors are cyan, magenta, yellow, and black.

A set of primary colors is a set of colorants or colored lights that can be combined in varying amounts to produce a gamut of colors. This is the essential method used in applications that are intended to elicit the perception of diverse sets of color, e.g. electronic displays, color printing, and paintings.
The colors on the red side of the wheel are warm; the green side of the wheel has the cooler colors. These color temperature designations are absolute. More subtle color temperature relationships are relative, meaning that each color on the warm side of the wheel can be known as cool, and colors on the cools side of the wheel can be known as warm depending on the relationship to their neighboring color. Colors from the same hue, for instance red, can also be warmer or cooler than one another.
