Back when I had tv, I watched a nature program about predators in Africa. I remember seeing a clip of “what the lion sees” in black and white, explaining the effectiveness of a zebra’s camouflage. I think I also remember reading that dogs are colorblind.
I’m curious about what other animals are, or aren’t colorblind. Horses, in particular. Any help?
Cecil Adams (you’ve heard of him?): Are cats and dogs really color-blind? How do they know?
Yes, I’ve read the article. There is no mention of horses, however, and I have not turned up anything in a web search. I should’ve phrased it as a more specific question. There’s a point I’d like to refute in a unimportant newspaper editorial, if horses are indeed colorblind.
I can’t vouch for its veracity, but the link below says that horses are colorblind. (No source is given.) http://www.visionsite.org/cons/grade1c.htm
The page I linked to above is wrong. Horses are dichromats, and not totally colorblind.

Okay, found it in the Encyclopedia Britannica. Hedgey, though.
“Like human vision, the horse’s vision is binocular, but only in the narrow area directly forward, and evidence suggests that it does not register colour.”
Good thing I previewed. I’ll go check that out. Thanks b-phage! And the green difficulty works for my purposes, anyway.
