Here's what I get:
IDL> help, /device
Available Graphics Devices: CGM HP LJ NULL PCL PRINTER PS REGIS TEK X
Z
Current graphics device: X
Server: X11.0, The X.Org Foundation, Release 60802000
Display Depth, Size: 24 bits, (1280,1024)
Visual Class: TrueColor (4)
Bits Per RGB: 8 (8/8/8)
Physical Color Map Entries (Emulated / Actual): 256 / 256
Colormap: Shared, 16777216 colors. Translation table: Enabled
Graphics pixels: Decomposed, Dither Method: Ordered
Write Mask: 16777215 (decimal) ffffff (hex)
Graphics Function: 3 (copy)
Current Font: <default>, Current TrueType Font: <default>
Default Backing Store: Pixmap.

I should note that I have problems like this whenever I use any form
of color table. I routinely make contour plots with a greyscale
colortable, and when I write those to png files, the background always
goes blue. Not such a big deal there, but when I am trying to use the
colors to represent things, I have trouble.

Thanks!

Kathryn
