Thanks to everyone who responded to my question. If I had only posted
sooner I could have saved a lot of time . . .

Then plot over top of this!

You have to load the color table *after* you use the DEVICE,/COLOR command
One way to change the color of the background in the PostScript device is to
start off by displaying a single pixel of the right color which fills the page,
e.g.
B = [0B]
TV, B(0:0,0:0), 0, 0, XSIZE=!D.X_SIZE, YSIZE=!D.Y_SIZE, /DEVICE
followed by the rest of your plotting commands.
