CMYK
A color representation scheme (or color space) in which cyan,
magenta, yellow, and black are combined to create full-color
images.
colorant
A pigment, dye, phosphor, or other such substance that produces
a color. Colorants are like building blocks of colors—for example,
green is composed of cyan and yellow, so cyan and yellow can be
considered colorants that make up the color green.
color cast
The predominance of a particular color that affects the whole
image in the original, proof, or reproduction. A color cast is due to
an excess of a color pigment or light. It is most obvious in gray and
near-gray areas.
color channel
