Desktop Color Primer

Color Reference Guide for C9800 - 83

Many computer applications 
include dialog boxes in which 
you choose colors by 
manipulating hue, saturation, 
and brightness. For example, 
some applications use a color 
picker that can be 
reconfigured according to 
your preference (as shown 
below).

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 Fiery and offset presses, are based on the 

subtractive color model

.
