Dichromatism is a disorder. Our brains expect a trichromatic signal and when it only receives dichromatic information the hues are “repeated” because a cone (usually the one responsible for green) is not available. In people with green-weak color blindness this makes green look like a “weak” reddish hue. Tetrachromats’ brains are still expecting a trichromatic signal but they get more information than is expected. That means that the image contains more information or detail but the colors are not nee colors.
- masklinn 7y agoThat’s not how brains or vision work. The brain is not “hard-coded” for trichromatism. Were that the case we would not be trichromats in the first place.
- HeWhoLurksLate 7y agoOur brains are rather complicated, interesting things- and probably do something like wire themselves up to whatever "sensors" are available.
- klyrs 7y agoWhat if trichromatism is also a disorder, that afflicts the vast majority of humans?
