Clearly, if you change the entire color table, the desktop cannot be drawn 
in its original color and pattern.  The most you can hope for is a best 
guess of what the colors would be in the new table.

If the latter is what you need, you can come close by using the Palette
Manager.  Don't mess with the color table directly, but associate with your
window a palette of tolerant colors with the tolerance of each set to zero.
Every time the palette is changed, various managers and applications 
themselves will try to redraw the world to look as good as possible in the
new world.  Sometimes they even come close.  

However, you may find the flashing caused by the redrawing annoying.  NCSA 
Image uses a different approach which avoids the flashing but which leaves 
strange icon colors when run under MultiFinder.
