What colors do horses see? Read here!
As we have already seen, the vision of a horse is different from that of a person. And the colors of the horse do not see how we are.
The eyes of a horse are different from the eyes of a man
Photoreceptors are divided into 2 types: cones and rods.
The sticks are responsible for black and white vision, but can even respond to very low light. They make it possible to see at night and at dusk, but in low light they do not allow to distinguish colors.
Cones are responsible for the clarity of the contours of objects and the perception of color.
If the animal is nocturnal, it has more rods than cones. If the animal is active during the day, cones prevail. Therefore, it is safe to say that the horse does not have black and white vision. But to understand what colors she sees is much more difficult. After all, cones are heterogeneous, in addition, there are many related factors.
The conducted experiments proved that some colors of a horse distinguish better, others - worse.
For example, B. Grzimek conducted a study in which it turned out that yellow strips 0.5 cm wide were seen from a distance of 3.3 meters. But they noticed a blue strip from the same distance only if its width was at least 2 centimeters.
Most likely, the yellow color of the horse can be distinguished best. The second place is green. Next comes blue, and only then red.
In general, we can say that horses do not see as clearly as pigs, dogs and people.
