Deciding which color correction to use
Color printers and computer display screens produce color differently.
Printers use the subtractive primaries CMYK (cyan, magenta, yellow, and
black), and produce color when light is reflected off the paper. Computers
use the additive primaries RGB (red, green, blue) with a light-emitting CRT
screen. The printer and the computer screen each have a different range of
possible colors they can produce, with some overlap between them.

Software application packages specify color in different ways, for example
as CMYK or RGB, or they may give you a choice. Get to know your
applications so you can work more efficiently.
