    Is the difference in the eyes or brain?

      The eyes. Tetrachromats have a 4th kind of cone in the eye.

      It’s a fourth cone in the eyes. Interesting that the brain just rolls with it being present. Something similar was done to give squirrel monkeys the missing cone they need to see red: https://www.nationalgeographic.com/science/article/gene-therapy-gives-full-colour-vision-to-colour-blind-monkeys
