The one color you have doesn't happen to be red, does it?
I would guess a DEVICE, DECOMPOSED=0 might help. Otherwise,
there is a LOT of color information on my web page.

If your version of IDL supports it, you can try setting
the IRREGULAR keyword on your contour command. Otherwise,
you will have to grid the data yourself with TRIANGULATE
and TRIGRID.
