COLOR_MODEL

This variable is typically used when a character-based application is moved to a graphical environment. Use the COLOR_MODEL setting to perform uniform changes to your program's color scheme. These changes are represented by rules that act on your colors. An example of a rule is "exchange the foreground and background colors". Use COLOR_MODEL to change your color scheme in a global way.

The default color model is model 0. It causes no changes to occur to your color scheme. The remaining 10 models are 1 through 10.

• The odd-numbered models transform only those parts of your program that are entirely black and white. Any character position that contains any color is left unchanged.
• The even-numbered models apply the changes regardless of color. When selecting a COLOR_MODEL, you can ignore the even-numbered models if you are satisfied with the color portions of your program.

Each color model is actually a composite; it's the equivalent of two or more configuration file variable settings:
