Here it is. 

#include "allegro.h"
int main()
{
  PALETTE pal;
  BITMAP *bmp;
  char *buf="test.bmp";
  int i;

  allegro_init();
  install_keyboard();
  i=set_gfx_mode(GFX_AUTODETECT,800,600,0,0);
  if (i<0) {
      allegro_exit();
      printf("Graphics initialization error: %s\n",allegro_error[i]);
      return(1);
  }
  bmp=create_sub_bitmap(screen,0,0,800,600);
  for (i=0;i<16;i++) rectfill(screen,i*30,0,(i+1)*30,100,i);
  get_palette(pal);
  save_bitmap(buf, bmp, pal);
  readkey();
  return(0);
}

It seems like there is a bit more blue than red and green, cause white is
very light blue and others also seems affected.
