I suppose you could use several atmospheric media, each one attuned to a 
different RGB value to simulate a frequency-dependent effect.. but the 
scenes would be horribly slow to render.

ISTR that someone was working on frequency-dependent scattering a long 
while back, but I don't remember if the work was ever finished, and if 
so, it wasn't incorporated into the Megapatch or 3.5.
