Yes, this is why I use optimized pallettes. The GIF images on the site
each have their own optimized pallettes, which in each case winds up
being only a few colors actually being used in each graphic. Netscape
interprets these fine, the problem is IMHO in JR's particular video
setup. He may just have his monitor's color, or other settings, not
calibrated properly.
