I'm not sure I understand what are you saying.  Are you saying that 256 
is an incorrect value?  On X, x-display-color-cells returns what 
DisplayCells returns, so Emacs isn't ``guilty'' ;-)

The number of colors you have on a 24-bit display is much larger than 
what rgb.txt shows, but the number of colors that are available in the 
colormap is typically smaller, so 256 doesn't sound very wrong to me.
