How indeed? I am using the same colors and I have copied
the table into the postscript device.

Martin's solution is to generate a discrete color bar using
POLYFILL. I am sure this will work but I would still like
to know why there is a difference between a color bar created
with TV and one with a plot routine (POLYFILL, CONTOUR, PLOTS).
Whether the bar is made up of continuous colors or a discrete
number of colors should not make a difference, should it?

I don't know enough about postscript to know what is going
on inside the file.
