You never addressed the evidence I gave regarding how magenta is an invented color. What do you think the world looks like to birds, which are tetrachromats? Do you think they still see various combinations of reds, greens, blues? What do you think ultra violet look like to them? Different brains produce different sensations, and there are far more possible brains than there are types of fundamental physical phenomenon.
