Hi Greg, I'm the GEMPAK developer here at Unidata and I think I can help you do what you want. The default GEMPAK color table ($GEMTBL/colors/coltbl.xwp) is referenced by all GEMPAK programs for what colors to use to draw graphics. This file must only contain 33 lines, but the RGB definitions can be anything you want. If you're exporting a color table to GEMPAK, it *must* be in the same format as coltbl.xwp. If you attach the new color table back to this message, I can take a look on my end why it may not look right.

The LUTFIL option is only for sat and radar as I understand it.
