You have a fundamental problem shared by everyone with 8-bit
workstations.  You can't do it all of the time.  You can only
approximate.  It is not a problem with focus.  Only one colormap
can be installed at any given time (with most hardware.  I believe
the Silicon Graphics can have 16 at one time).

You might try bringing up your X server with an 8-bit TrueColor
Visual.  This will give you very choppy images, but it will do it.

If this is unstatisfactory, I can give you a program that addresses this
very problem and will display very nice images that share the default
colormap.
