We have noticed the same problem.  We find it isn't only x0 that has
the correct colours, but whichever monitor is opened first.  (Try
opening x1 first, then x0, and see how the colours look.)  We noticed
too that it isn't just the intensity of the colours that is off, but
in some cases two shades of a colour will come out the same, so detail
is lost in a many-coloured map.

I suspect now that it has to do with the way XWindows assigns colours
to windows when requests are made.  Is it possible that the first
monitor gets the colours it asks for, while subsequent monitors get
what X thinks is a "close approximation" to the requested RGB value?
Remember that the RGB requests are 24-bit, while the X-terminal can
only show 256 colours at a time.  

The question is, why is X not assigning the same colour set it gave
to the first monitor opened?  Are there any X gurus, or GRASS code
experts, who can help us out?
