I don’t know how it came about but I wondered the other day if horses see in colour or black and white.
Here’s what I discovered…
Horses do see in colour but not the vibrant colours that we see. Horses for one cannot see the colour red, however their eyes pick up the blue and green hues of all other colours this is called dichromatic vision, most mammals including horses, dogs and cats are dichromats, and yes you read right dogs do see colour!
Humans have what is called trichromatic vision allowing us to see in full colour we share this with several primates such as chimpanzees, gorillas and orangutans but most fish also are trichromats.
Monochromatic vision is black, white and grey. As most of us know bulls are one animal that can only see in black and white but there are many other animals that share this vision including seals, sea lions, dolphins, whales, hamsters, raccoons and bats.
