Unknown to me but it was my impression that each plane was it's own 
memory map and you write to each plane in turn to get the bits set for 
colors. It would also depend if they are arranged as bit per pixel or 
some larger order of bits say a byte or word.  I'd presume that to get
more than monochrome single intensity you would have to go for at least 
several bit per pixel if only for gray scaling.  Color would be a minimum
of 1 bit per color and I'd expect 4 bits or 8bit for each colors 
intensity.  The linear map that P.A. posted is only a fraction of the 
puzzle.
