DOES COLOR EVEN EXIST? WHAT YOU SEE IS ONLY WHAT YOU SEE
good article, nicely summing up a whole lot of things, especially the philosophical point that answers become harder to find the closer you look (or with every new answer, a dozen more unfold that were unseen before) - and the other point that too often, experts profess knowledge that they do not have.
add to that "Modern biologists have given us a couple of models. Trichromacy" has been tipped off balance too with the discovery I mentioned back in 2012, that some of us have tetrachromic vision - a fourth sensor exists..
