Here's one inspired by SCO setcolor I whipped up awhile back.  It's
not very well written nor has lots-o-features but you get the source
and may help you.  Enjoy.

/*
 *  color.c - Set color of monitor.

 *  This code is hereby transferred to the public domain.  Make big money
 *  or anything else you like.	Even pretend you wrote it because I don't
 *  want to admit this is mine. :-)  Some pretty obvious improvements can
 *  be made, but it just doesn't matter to me right now.
 *
 *  This has been compiled under MSC 4.0.
 *
 *   Param	Desc
 *	8	Invisible (black on black) display.  Yeesh.
 *     30	Foreground black
 *     31	Foreground red
 *     32	Foreground green
 *     33	Foreground yellow
 *     34	Foreground blue
 *     35	Foreground magenta
 *     36	Foreground cyan
 *     37	Foreground white
 *     40	Background black
 *     41	Background red
 *     42	Background green
 *     43	Background yellow
 *     44	Background blue
 *     45	Background magenta
 *     46	Background cyan
 *     47	Background white
 *
 *   Bugs:  Has stupid notion that the default color of screen is green.
 *	    Aren't they all? :-)
