Chris,

The colorbar information for satellite pictures is actually hardcoded into
the $GEMPAKHOME/src/gemlib/im/imdrop.f routine (3 lines from the bottom)
to use color 1 for the colorbar.

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.
