$COLOR

$COLOR is a metacommand that adds named color constants in a program.

Syntax

$COLOR:0

$COLOR:32

Description

• $COLOR:0 adds constants for colors 0-15. The actual constant names can be found in the file source/utilities/color0.bi.
• $COLOR:32 adds constants for 32-bit colors, similar to HTML color names. The actual constant names can be found in the file source/utilities/color32.bi.
• $COLOR is a shorthand to manually using $INCLUDE pointing to the files listed above.
• Prior to QB64-PE v0.5.0, $COLOR was not compatible with $NOPREFIX.
• Since QB64-PE v0.5.0, $COLOR can now be used with $NOPREFIX, with a few notable differences to three conflicting colors -- Red, Green, Blue.

Red would conflict with _RED, Green would conflict with _GREEN, and Blue would conflict with _BLUE, once the underscore was removed from those commands with $NOPREFIX.

To prevent these conflicts, the COLOR values have had NP_ prepended to the front of them, to distinguish them from the non-prefixed command names. All other color names remain the same, with only the three colors in conflict having to use NP_ (for No Prefix) in front of them.

Examples

Example 1

Adding named color constants for SCREEN 0.

$COLOR:0 COLOR BrightWhite, Red PRINT "Bright white on red."

Bright white on red.

Example 2

Adding named color constants for 32-bit modes.

SCREEN _NEWIMAGE(640, 400, 32) $COLOR:32 COLOR CrayolaGold, DarkCyan PRINT "CrayolaGold on DarkCyan."

Example 3

Adding named color constants for 32-bit modes (with $NOPREFIX in effect).

SCREEN _NEWIMAGE(640, 400, 32) $COLOR:32 $NOPREFIX COLOR NP_Red, White 'notice the NP_ in front of Red? 'This is to distinguish the color from the command with $NOPREFIX. PRINT "Red on White."
