NAME
       set_color - Sets the specified palette entry to the specified RGB triplet. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void set_color(int index, const RGB *p);

DESCRIPTION
       Sets  the specified palette entry to the specified RGB triplet. Unlike the other palette functions this doesn't do any retrace synchronisa-
       tion, so you should call vsync() before it to prevent snow problems. Example:

	  RGB rgb;
	  ...
	  vsync();
	  set_color(192, &rgb);
