palette_color(3alleg4)						  Allegro manual					    palette_color(3alleg4)

NAME
       palette_color - Maps palette indexes into the current pixel format colors. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       extern int palette_color[256];

DESCRIPTION
       Table  mapping  palette index colors (0-255) into whatever pixel format is being used by the current display mode. In a 256-color mode this
       just maps onto the array index. In truecolor modes it looks up the specified entry in the current palette, and converts that RGB value into
       the appropriate packed pixel format. Example:

	  set_color_depth(32);
	  ...
	  set_palette(desktop_palette);
	  /* Put a pixel with the color 2 (green) of the palette */
	  putpixel(screen, 100, 100, palette_color[2]);
