How Carp Sees the World—or, Come Laugh at the Disabled :marseycarpdead:

The Fish unwisely revealed in his recent thread that he is physically disabled:

I’m partially colorblind and I always thought your name was blue lol. Blue-purple are my worst colors

Amusingly, actual carp can see more colors than humans, up into the near-ultraviolet: Carp, therefore, is strictly visually inferior to carp.

Blue–Purple discrimination is worst in protanopes—people who have wonky or absent red-sensitive cells in the retina. Since we don't know how 'partially' colorblind he is, I uncharitably assume he is maximally impaired in red perception.

And this is how he sees the world:

Slight color blindness. Wouldn’t be able to tell cancerous cells from normal cells on an H&E and no way I could give an accurate KI-67.
