I am trying to implement a 256 element PseudoColor colormap under X/motif 
for image processing applications.  The palette will initially be linear
and via pseudocolor, contrast, and other imaging operations may be dynamically 
altered.  Using the calls XCreateColormap, XAllocColorCells, and XStoreColor 
I have been able to create a linear mapping.  I then use XSetWindowColormap 
to associate this mapping to the toplevel application shell.  Unfortunately, 
the colors used by the window manager have been lost.  

Does anyone know how to preserve the colors used by the motif window manager
within my 256 element colormap?  Basically, I would like to create a (256 - N) 
element colormap.  Where N would be the number of colors needed to preserve 
the 3D-look, menus, etc. used by the mwm.  Due to the dynamic nature of the
imaging colormap, sharing of colormaps does not seem like a good approach.  
I'd really just assume that N out of my 256 are reserved for the window manager.
Hopefully N won't be to large (16 or less?).

If anyone has any suggestions, references, etc., I'd really appreciate it.

Thanks!
