set_palette - Man Page

#include <allegro.h>

void set_palette(const PALETTE p);

Sets the entire palette of 256 colors. You should provide an array of 256  RGB structures. Unlike set_color(), there is no need to call vsync()  before this function. Example:

   BITMAP *bmp;
   PALETTE palette;
   ...
   bmp = load_bitmap(filename, palette);
   if (!bmp)
      abort_on_error("Couldn't load bitmap!");
   set_palette(palette);
