Additive (Emitted) and Subtractive (Reflected) Color Models

All light is a mixture of red, green, and blue, which is normally called the RGB

model. When red, green, and blue are of equal intensities, the RGB color model

produces white.

RGB is also called additive or emitted color. The colors on your computer

screen are produced by varying the intensities of RGB.

Printed color is a mixture of cyan, magenta, and yellow, which is normally called

the CMY color model. When mixed in equal proportions the CMY color model
