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.
