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 runtime configuration variable settings:

• COLOR_MODEL "1" is equivalent to:
  COLOR_TRANS "5", INTENSITY_FLAGS "34", and BACKGROUND_INTENSITY "1".
• COLOR_MODEL "2" is equivalent to:
  COLOR_TRANS "4", INTENSITY_FLAGS "34", and BACKGROUND_INTENSITY "1".
• COLOR_MODEL "3" is equivalent to:
  COLOR_TRANS "3" and INTENSITY_FLAGS "34".
• COLOR_MODEL "4" is equivalent to:
  COLOR_TRANS "1" and INTENSITY_FLAGS "34".
• COLOR_MODEL "5" is equivalent to:
  COLOR_TRANS "1" and INTENSITY_FLAGS "129".
• COLOR_MODEL "6" is equivalent to:
  COLOR_TRANS "1", INTENSITY_FLAGS "129", and BACKGROUND_INTENSITY "2".
• COLOR_MODEL "7" is equivalent to:
  COLOR_TRANS "3" and INTENSITY_FLAGS "161".
• COLOR_MODEL "8" is equivalent to:
  COLOR_TRANS "1" and INTENSITY_FLAGS "161".
• COLOR_MODEL "9" is equivalent to:
  COLOR_TRANS "3" and INTENSITY_FLAGS "193".
• COLOR_MODEL "10" is equivalent to:
  COLOR_TRANS "1" and INTENSITY_FLAGS "193".
