set_palette - Sets the entire palette of 256 colors. Allegro game programming library.

       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);
