Color in text console

[Cruncher]

I've got aalib installed and games like prboom or quakeforge (nq-sdl) use it by default, which is what I want, and I can alter the text size to get a reasonable resolution.   Does anybody know how to get color?    The text console will do color (eg. ls -l --color=auto produces a color listing of files).  And if I run these games packages without aalib installed, they run in a normal kind of svga mode, in color.   But with aalib they run in black, white and grey.
