Well, now that I read this a little more closely,
I think the problem is that you are trying to
display these images on an 8-bit display. This
makes the problem more difficult, but not
impossible.

What you need to do is make all your images and your
color bar share the same color space. I think the
sensible way to do this is to use COLOR_QUAN with
the CUBE keyword set to 6 on all your image. This 
will quantitize your colors to 216 values that 
can faithfully (more or less) represent both the 
images and (I presume) color bar.

Cheers,

David
