you really must set color 0 to some other color, and you want the
background to stay black, you will have to clear the screen to another
color that you have set to black before doing your other palette
settings. And no, this is not a Allegro specific thing. It's been true
in every other graphic program/lib I've ever seen, even in non-VGA
modes. Hope this helps somewhat.
