A search of the archives of this newsgroup will soon reveal
that there is nothing whatsoever like this, and that, in
fact, a number is about the least useful thing you can
have with respect to colors in a color table. :-)

If you want the colors to be right, load your color table
and save the *color vectors*:

Loadct,5
TVLCT, r, g, b, /Get

Then, later, to return to the colors:

TVLCT, r, g, b

If you *have* to know the number, save that, too. :-)

Cheers,

David
