i wonder if choices amongst metamers might have secondary effects we don't know about...

like given two renders of the same image with different metamer selections, are there possibly subconscious impacts to mood or feeling between them. do different spectral envelopes that produce the same percept result in different demands or representations in the ventral stream which then could (or may not) manifest in nonobvious ways?

I can't think of a mechanism by which this could happen, since the cone pigments will have the same absorption rates in either case. There's no signal that the brain could use to behave differently.

i just reread about the retina and i think you are correct.

i was under the false impression that the transfer function for each group of cones was a function of some processing in higher layers of the ventral stream.
