Well, those specifications don't make too much sense, since
there is no "color" at index 260. But, what I *think* you
are trying to do is something like this:
cgLoadCT, 39, Clip=[50,254], NColors=20, Bottom=1
cgColorBar, NColors=20, Bottom=1, /Discrete, $
Range=[Min(level),Max(level)], Charsize=0.75
Cheers,
David
