I don't know about everyone else, but when I define my own color table I
always make color index 0 black and index 255 white. Colors 1 - 254 are
the ones that get changed. No matter how you change the other colors,
black and white are always the same -- you wouldn't believe how helpful
that has been... or maybe you would?
