This has been a popular question. NeWS has a static color table.
When you bring in a foreign 8 bit color image, it simply picks
close colors. 24 bit files are dithered into the static color table.

I don't believe there is any dither taking place for 8 bit images.

The only solution would be to somehow change the color lookup table
on the display, without the help of NeWS. Of course everything else
on the display will look like junk.
