Why not define a full-color pigment function that uses average {} and some kind
of function related to the distance from some point from the camera?
Then you could assign wavelengths and phase shifts, and get the overlapping
color effect?

If anyone could do it, these people could.

I would imagine that WFP, TOK, and Jerome Grimbert would have an idea or two.
