Tom, You need to create the $GEMTBL/luts/mdr.tbl file with the lines I provided. This will define the 6 vip color levels for the image. $GEMTBL should be defined as $NAWIPS/gempak5.4/tables in your environment by the Gemenviron script. In the $GEMTBL directory are subdirectories sat, luts, color, grid, parms, etc. If you don't see these subdirectories, then you are in the wrong place- or are not looking at Gempak5.4.
