The last time I spoke with the ISC technical people, they stated that
they didn't support 8-bit color because it was too slow.  Having used
a Sun386i with 8-bit color, let me tell you that they're probably
right.  A lot of optimization needs to be done to make it acceptable.
ISC seems to have done fairly well so far, though.

You shouldn't have to do anything special; you'll just have a pallette
of 256 colors to work with instead of 16 unless you're doing something
like colormap-based double-buffering.

If you need fairly well-written color code, I have a bunch of it
laying around; one such program is xloadimage, an image display
utility, which was recently posted on comp.sources.x if you want to
grab it.  It has a LOT of color support for n-bit displays.

Happy hacking,
