I want to display some 24 bit color images on my Mac and Sun.  Both
machines have 8 bit display boards.

What is a good algorithm or method for determining the best (or a
very good) colormap given a 24 bit image?  I'd like the algorithm
to work for various sized colormaps (although 256 will be most
commonly used).

Is such an algorithm built into 32 bit Quickdraw?  Are there any
standard algorithms for doing this?  How about any technical 
references?

Thanks
  mike
