It's even simpler: tvscl, -array does the same.
The other idea would be the usage of an inverse color table like this:
tvlct, r, g, b, /get
tvlct, reverse(r), reverse(g), reverse(b)

Hi!
I do not know how you should change the IDL settings in order to do this
every time. However, until someone comes up with a better solution you could
use this line (assuming array of dimension 2):
tvscl, max(array)-array
