I've taught the psychology of perception at various institutions and I agree that it's a very interesting subject (not that we needed to go into the issue to the extent you would, naturally).
I agree about colour perception and the range of abilities people have. Similarly a (then) girlfriend's aunt insisted she could not tell the difference between stereo and mono.
