DESKTOP COLOR PRIMER 66

Additive and subtractive color systems

Color devices used in desktop publishing and printing simulate the range of visible colors

using a set of primary colors that are combined to create other colors. There are two methods

for creating a range of colors from a set of primary colors. Computer monitors and scanners

are based on the additive color model. Printing technologies, including the Color Server and

offset presses, are based on the subtractive color model.

Additive (RGB) color

Color devices that use the additive color model create a range of colors by combining varying

amounts of red, green, and blue light. These colors are called the additive primaries

(illustrated in the following figure). White is created by adding the maximum amount of red,

green, and blue light available. Black occurs wherever all three colors are absent. Grays are

created by adding equal amounts of all three color together. Combining varying amounts of

any two of the additive primaries creates a third, saturated hue.
