Interesting colours coming out of it - a while back I suspected I have https://en.m.wikipedia.org/wiki/Tetrachromacy since I was able to describe colours more vividly that others, and certain plants for me like Verbena have a glow around them.
I'd love it if there was someone with tetrachromacy who also knows a bit about color theory and perception and can talk about it!
How do you describe the experience scientifically? Do you get a whole bunch of extra colors you'd want to give a distinct name since they're so clearly different from the standard trichromatic colors?
Is a computer screen annoying because it can only produce a subset of the colors you can see?
Do you notice that you have a fourth parameter or dimension in the colors you see, so would want a 4th component in RGB, HSV, etc... color sliders? E.g. for our HSL, would the fourth parameter be hue-like, saturation-like, lightness like or some completely novel other thing? If hue like, do the hues also form a 2D sphere or torus like topology similar to how our trichromatic hue forms a circle?
I'd expect at least twice or 3x as many named colors, since for every regular color (red, green, blue, yellow, orange, purple, pink, grey, brown, black, white, ...) , you'd have a fourth dimension altering it that can be low, medium or high in value ...
E.g. for our yellow, you'd have yellow with not the extra signal, a bit of the extra signal or lots of the extra signal. Is this the case or not? Perhaps the overlapping reduces it, but as said in the article trichromats also have overlap yet we definitely see a lot more distinct colors than dichromats.
Some people with two X chromosomes have this ability. And all birds.
If you are bored, try to get Gemini/claude to make a color wheel for birds or tetrachromats.
An aside: Recently I learned that birds are reptiles. That hurt my brain and I’m still recovering. Especially since the modern dinosaur exhibit claiming this fact contradicted the 1980s era reptiles exhibit down the hall (both at the British museum).
I think I would make a color triangle, except I would remove blue from it, and instead have the corners be three different colors in the red-green part of the spectrum. I guess 530, 545, and 560nm.
