Horse eye colors
Most horses have brown eyes. Many equines and some breeds can also have a blue color. In rare cases, the color can be green or purple.
Blue eyes are common to all horses and coats. Some horse breeds are more likely to have blue eyes. It’s very common in horses with spotted coats such as paint and appaloosa, and in specimens with light coats.
The colored part of the eye is the iris that surrounds the pupil. The pigmentation of the iris depends on the concentration of melanin. If the eye is dark there is a greater amount of melanin, when it’s lighter, the amount of melanin that pigments the iris is less.
Heterochromia and Mosaicism of the eyes
In addition to blue eyes, horses can have both heterochromia and mosaicism.
Heterochromia is when they have different colored eyes. Normally one eye is blue, the other black or brown. Heterochromia is due to a different concentration of melanin in the two eyes.
It has no influence on the quality of sight. However, if it occurs over time, it can result from pathological problems or trauma.
Mosaicism is when the horse has two different colors in one eye. The iris is bichromatic. Mosaicism occurs from birth. It’s transmitted genetically, however, if it occurs after birth it could be an alteration of the iris following a trauma or the manifestation of pathologies.
All mammals can exhibit mosaicism.
