This article should explain it for you:

http://www.dfanning.com/color_tips/lineinct.html

But, really, with a contour plot like this, you should
only be loading the contour colors into 25 slots in
the color table:

LoadCT, 20, Colors=25, Bottom=1

and later:

Contor, C_Colors=Indgen(25)+1, ...
Colorbar, NColors=25, Bottom=1, ...

Here is an article that explains why:

Cheers,

David

Isn't this one of those situations where you reserve a color or two at
the end of the color scale, make one of those colors be black and then
use that index (which is then something >= than !d.table_size) for
your axes? If you want to frame your colorbar in a color that does
not show up in the colorbar, then you will need to access a color
which is not found in the colorbar.
