tvlct, r, g, b, /get
This actually returns the color vectors rather than the color table
number. To return to the color table, just issue the same command sans
the /get flag.

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
