Do Baby Horses Change Color as They Age

Horses are majestic creatures that have captured our hearts for centuries. They are not only useful for transportation and work, but also make great pets and companions to humans. As these beautiful animals grow, it is not uncommon to wonder if their coats change color as they age. One common question that horse lovers ask is, do baby horses change color as they grow?


To understand how a horse’s coat color changes, it is important to first understand the genetics behind it. Horses possess two copies of each gene, one from the mother and one from the father. The genes that control a horse’s coat color are complex, but we do know that the coat color ultimately depends on the presence or absence of melanin, a pigment that determines the color of the horse’s hair and skin.


When a horse is born, its coat will either be a solid color or have a spotted or striped pattern. However, some horses are born with a coat color that will change as they grow. One prime example is the gray coat color, which is actually a progression of a horse’s original color as it ages. Gray horses are born with a solid coat color, but as they age, they will gradually turn gray due to the loss of melanocytes, specialized cells that produce melanin. This can occur over several years until the horse appears completely gray.

Another color change that can occur in a horse’s coat as it ages is the lightening or darkening of their existing coat color. This is known as a fading coat color and happens due to the sun’s UV rays impacting the pigment in the hair shaft. Chestnut horses tend to have a lighter coat color as they age, while black horses can frequently develop a reddish tone.

As previously mentioned, the genetics behind horse coat colors are complex, so it is impossible to determine how every horse will change color over time. However, there are some coat colors that are known to remain stable throughout a horse’s life, such as bay, chestnut, and black. These colors will not typically change as the horse ages.


While not all baby horses change color as they age, it is not uncommon for some horses to develop a different color or pattern. Gray horses tend to be a prime example of a coat color that changes over time due to the loss of melanin, while others can have a fading coat color, such as chestnuts.

It is important to remember that the science behind horse coat colors is extremely complex, and not every horse is bound to change color. Regardless, baby horses are adorable no matter what color they are, and we love them all the same.
