Which type are you?
Your twins: cat, dog, horse and more. Like you, they see reds and greens merge.
No twin on our list yet. We only match animals where reds and greens merge, so we cannot pair you up.

Do dogs see like colour-blind people?
In one way, yes: for a dog, reds and greens merge, as they do for people with red-green colour blindness. The dog sees mostly blues and yellows. Red and green look alike. Their eyes are built differently from yours, so the match is not exact.
Which animals are colour-blind like me?
Every animal in the list above. They all have two colour types in their eyes, one for blues and one for longer colours, so reds and greens merge. 144 animals on this site fit.
What if I have tritanopia?
Then blues and greens merge for you instead. We have not matched that type with animals, so there is no twin list for it yet.
