Contrary to popular belief, dogs don't just see in black and white. They can distinguish between yellow and blue.
Color blindness, common in humans, is due to abnormalities in color-detecting molecules, known as cones, in the retina.
The idea that dogs see only in black and white has been debunked. Dogs can see some colors, just not as humans do.
Dogs' eyes have evolved for nocturnal hunting, with more rods for low-light vision. This affects their color perception.
Dogs are dichromatic, with two types of cones. They lack red-green cones, affecting their perception of these colors.
Dogs can distinguish yellow and blue from green. This explains their preference for yellow and blue toys.
Knowing dogs' color perception can help in choosing the right colored toys. Avoid red or orange as they appear brownish-gray to dogs.
