It seems to me that if a board supports 16-bits/pixel that it would be
better to have the colors map directly rather than going through a
mapping table. With 5 bits each for red, green and blue that would
give you 32k colors to work with one bit left over. This would eliminate
the overhead of setting up the color mapping table as well the
hardware to do the mapping.
Does anyone know how many different colors a normal monitor can display
that the human eye can actually tell apart?
