Yep, you bet. We have a 'planned' expansion path for the architecture
which does include better color. However, other enhancements are in line
before we get to this one. So do not hold your breath. Also keep in mind
that the Amiga is primarily an NTSC video box, not a film box. I'm
sorry, but if you want Lucasfilm quality, you'll have to go elsewhere.

As a breif aside, you should look at the '83 SIGGRAPH proceedings which
contains a ( now classic ) article describing color compression in
images. The article deals with the 'Median Cut' algolrithm for color
table entry allocation. Very impressive two bit per pixel color images
are presented. 

If you use the techniques in this article, and the hold and modify mode
of the amiga, you can acheive surprising results. Sure this is compute
intensive, but it can give you some of the best results I've ever seen
on an Amiga.
