Adding Color Overview

The Intel® Fortran QuickWin Library supports color graphics. The number of total available colors depends on the current video driver and video adapter you are using. The number of available colors you use depends on the graphics functions you choose.

Color Mixing

If you have a VGA machine, you are restricted to displaying at most 256 colors at a time. These 256 colors are held in a palette. You can choose the palette colors from a range of 262,144 colors (256K), but only 256 at a time. Some display adapters (most SVGAs) are capable of displaying all of the 256K colors and some (true color display adapters) are capable of displaying 256 * 256 * 256 = 16.7 million colors.
