Uh, better get the book. Or, if you are short of cash,
better read my web page more thoroughly. :-)

: P.S. Try Device, Decomposed=0

Ah, yes, but that causes another problem. I am wanting to save the
resulting graphs as GIF files. However, with this option set to 0, using
tvrd to capture the screen (with the true keyword set to 0) returns the
luminosity, i.e. maximum value of RGB at each point. I'd like the actual
color returned.

What I need is a way of using tek_color normally, as given by
decomposed=0, but also being able to capture the window to a GIF somehow
without the colors getting messed up. What's the workaround this time?

See my web page for the tip of the millennium! :-)
