The Rainbow could do 4 colors from a pallette of 4096 in hi-res (800x240)
and 16 from a pallette of 4096 in low-res (384x240). The fact that the
pallette was not fixed was a major selling point with some because, in
low-res, properly dithered photographic pictures would look far better
than on the fixed-pallete IBM PC modes (CGA, EGA).
What's a CLUT, by the way? Not familiar with that acronym...
