          Tom has the correct diagnosis of the problem.  We ran into this
          problem not too long ago.  I do not claim to be an X-pert, but
          here are some solutions and non-solutions we came up with:

          1.   Do not run Motif(R).  Is it really worth it?  Does twm
               offer an alternative?

          2.   Get X-displays with 256 colors instead of 16.  We noticed
               that Motif(R) will gobble up 14 colors (it
               allocates them in shared mode so you will get lucky with
               some applications, especially if they do not use colors!).
               With a 256 color display, we do not have a problem.

          3.   If you have access to your applications source code, you
               should be able to install your own color maps.
               Motif(R) and other
               ICCCM compliant window managers will do wonders with false
               colors as you move your focus from one window to another.

          Let me know if you need any details re: the third option.
          Visually, it is not very impressive but it works.
