You can look at the souce of xloadct to see how it is done there, and make
whatever modifcations are needed for a 24 bit display. It is basically done
with
IDL> tvlct, r, g, b, /get
IDL> r = reverse(r) & g = reverse(g) & b = reverse(b)
IDL> tvlct, r,g, b

How about using the LOADCT procedure to load a reverse color table?
