The Colorbar routine just loads the colors in the current
color table. If there are colored lines there, then I presume
this arise from colors that have been loaded into the color
table. (Perhaps drawing colors for something else, would be
my guess.) You might have to refresh the color table before
you call the Colorbar procedure with the colors you want
to see displayed.

If the problem is drawing colors, you can avoid loading them
in the color table by using decomposed color (Device, Decomposed=1)
and using FSC_COLOR to select drawing colors.

Cheers,

David
