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 Fiery 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 (shown 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.
A familiar device that is based on this color model is the computer
monitor, shown in the following figure. Monitors have red, green,
and blue phosphors that emit varying amounts of light to display a
given color. Scanners create digital representations of colors by
measuring their red, green, and blue components through colored
filters.
