Use decomposed color. :-)

Or, if you insist on using the brain-dead TV command and
indexed color load your color tables just before you display
your image. With cgColorbar, use the AnnotateColor keyword
rather than the Color keyword to specify your drawing color.

But, really, use decomposed color. For everything. Really. :-)

Cheers,

David
