Ok Steve, Now I really now it's Friday and I'm totally braindead. It was in the help file all along (I swear I looked it up before and it was not there! :o)

Got it working. It was as simple as:
sset COLOR OF SCHEME 1 TO RGB(0,0,0,212,208,200), RGB(...
Sheesh. Thank goodness it's Friday! :o)

Tracy
