In the standard 640-mode color table, there are two grays, color numbers
3 and 12 (it's dithered, and %00 is always black and %11 is always white,
so %0011=3 and %1100=12).  These are -almost- the same shade (I don't know
why they aren't identical shades, actually).  Because of the dithering
they look different depending on the pixels next to them horizontally.
