????? You mean the colors are a little off?
I recal some coloring troubles on 8 bit (HP-UX) consoles. This was becasue
of the colormapping used in 8 bit mode. We solved that by loading a picture
with all colors on the background so the colormap was filled. There are
better examples.

I recal there are several tools to twiggle with the colormaps at runtime. I
think they work with Xvnc too. Try what you can do with the xset command in
a running vncserver.

The default is a file called 'rgb.txt' or 'RGB.txt' somewhere in the X tree.
