IMAGING GLOSSARY

Color model (imaging)

A method for producing a new color by mixing a small set of standard colors: sometimes called a color system. The most common color models are:

GRAYSCALE: white to black, with all shades of gray in between.

RGB: Red, green, and blue: this is an additive color model used by computer monitors, depending on a light source to produce color. Usually RGB values are specified as percentages or as values from 0 to 255.

CMYK: Cyan, magenta, yellow, and black; a subtractive color model and typical printing process colors, dependent on the light-absorbing properties of ink on paper.

See color space.
