I attended a session at the STC conference (actually two sessions) on
graphics (I do not have all the material here at work, so I'll post more
info when I find the papers):Warning: Contains Graphic MaterialWarning:
Contains (Really Complex) Graphic Material
A portion of these sessions dealt with the problem of "palette
shift." This problem comes about when you use two different sets
of colors; something you may not realize when you are capturing
or manipulating graphics. What is white in one palette can be green
in another. One solution is to set your graphics to 16 color (which has
been suggested). This gives you the same 16 colors used in the
Windows environment. Moving graphics from Windows package to
Windows package should not change your graphics.

Since these 16 colors can be pretty boring, you can actually change
the palette used for your graphics. (This is the portion of my story
for which I do not have the information at my fingertips. ) The
are fairly cheap. Most of us should already have the tools.

I believe that if your graphics have suddenly become "posterized" or
had a bad case of palette shift, the palette used to create the original
graphics was lost or damaged in some way. Also, if you see a "flash"
in the graphics color as you move between programs, you are also
experiencing palette shift.

More info as I find it.
