[GEMPAK #NAB-762187]: making colors based on rgb parameter for fline in gempak



Hi Jason,

The unexpected color is GEMPAK's input character limit being exceeded for the 
FLINE definition, so the last color remap does not take (;8=0:153:204)

When this happens it's best to move to a custom colorfile, a modified 
coltbl.xwp in the present working directory of your script. In this way you can 
control the specific RGB values of all colors rather than only a few.  I tested 
and confirmed this works, simply add this file to pwd and use 
FLINE=2;3;4;5;6;7;8
