The easiest way to set the satellite colorbar color from vanilla to something else is to run the gpcolor program and set color 1 to something that displays better on a white background, for example: colors=1=blue In reality, the clrbar should inherit the same information that is used for the radar image- but you'll notice that gpmap didn't provide the colorbar option for satfil and radfil. I'll look into a change for this in the future. Steve Chiswell
