The colors used in four-color process printing. Cyan, magenta, and yellow (CMY) are the three primary colors of the subtractive color process in which colored pigments are used to represent full color on the printed page. In theory, the combination of cyan, magenta, and yellow should produce black, but since color pigments are not perfect, the resulting hue is actually a dark, muddy brown. This is the reason why black is so important in four-color process printing because it assists the cyan, magenta, and yellow in creating the darkest hues, deepening shadows, and producing a true black text. Black is designated “K” rather than “B” to avoid confusion with blue, which is one of the primary colors of the additive color process (Red, Green, and Blue).
