Remember that voodoo2 uses 16 bits for its colour information, and that it
encodes its colour information in a lossy sort of way so that the
effective number is about 22 bits. Perhaps your similar shades of grey are
too similar for this lossy algorithm. The precise details of it have not
been disclosed.
