Color

The color command changes the color of the text and/or the background.

For example, to change the color of the text to blue, use the code color BLUE. The Hugo standard library defines the sixteen standard colors as:

Value	Color	Constant name	Sample	Value	Color	Constant name	Sample
0	Black	BLACK		8	Dark gray	DARK_GRAY
1	Blue	BLUE		9	Light blue	LIGHT_BLUE
2	Green	GREEN		10	Light green	LIGHT_GREEN
3	Cyan	CYAN		11	Light cyan	LIGHT_CYAN
4	Red	RED		12	Light red	LIGHT_RED
5	Magenta	MAGENTA		13	Light magenta	LIGHT_MAGENTA
6	Brown	BROWN		14	Light yellow	YELLOW
7	White	WHITE		15	Bright white	BRIGHT_WHITE

These colors can appear differently on different interpreters (or not at all). Some interpreters may also allow the user to define their own colors. These default colors have their own values:

Value	Constant name	What it is
16	DEF_FOREGROUND	Foreground defined by interpreter
17	DEF_BACKGROUND	Background defined by interpreter
18	DEF_SL_FOREGROUND	Status line foreground defined by interpreter
19	DEF_SL_BACKGROUND	Status line foreground defined by interpreter
20	MATCH_FOREGROUND	Whatever the current foreground color is (assumedly)

global TEXTCOLOR        = DEF_FOREGROUND        ! normal text color
global BGCOLOR          = DEF_BACKGROUND        ! normal background color
global SL_TEXTCOLOR     = DEF_SL_FOREGROUND     ! statusline text color
global SL_BGCOLOR       = DEF_SL_BACKGROUND     ! statusline background color
global INPUTCOLOR       = MATCH_FOREGROUND      ! input color

As you can see, games without custom color definitions automatically set their colors to these values. If you do change some colors in your game, it is best to change all of the color globals. There is no way for the game to know what the default colors are and therefore can’t tell if you have, say, BLUE on BLUE.

Menus

If you have menus, you may want to set the following menu color globals, too:

global MENU_TEXTCOLOR
global MENU_BGCOLOR
global MENU_SELECTCOLOR
global MENU_SELECTBGCOLOR
