Patrick,

The coltbl.xwp should have 33 colors in it, the first being the
background color, then the following 32 being the colors accessible
in your COLORS, LINE, FLINE etc colors. GEMPAK defines 3 color spaces-
Graphics, Radar, Satellite with 32, 20, and 95 colors respectively; so,
your tables for each have to respect those number of colors.

Otherwise, make sure your tables follow the correct columns.
See $GEMTBL/colors/coltbl.ptype for an example of a color table I use
for FLINE use in grid contours:
