If you are brand-new to the industry, attempting to learn the different horse breeds and colors may be confusing. You may see two horses that appear red to you but hear others calling them sorrel or chestnut. You may wonder whether there is a distinction between the two, i.e Sorrel vs Chestnut and if so, how can you tell? However, there are distinct differences between chestnut and sorrel horses, and once you learn how to spot these differences, distinguishing the two horses becomes relatively easy.
The differences between sorrel and chestnut horses are that sorrel is the lighter, brighter red hue of chestnut, while chestnut is a deeper, often reddish-brown color. Since sorrel stems from chestnut, it is easy to remember that all sorrels are lighter chestnuts, but all chestnuts are not sorrel.

The Difference Between Chestnut And Sorrel Horses
Sorrel and chestnut horses appear to be the same kind of red; after all, they have the same genetic makeup. However, some distinct differences between chestnut and sorrel horses make it relatively easy to tell them apart.
Sorrel horses are a specific shade of chestnut; they are usually much lighter in color and quickly appear red to the eye. Most sorrel horses have a copper-red colored coat, with their manes and tails generally much lighter than their coat or similar in color. Sorrel horses are genuinely described as a ‘true’ red color.

In contrast to this, chestnut horses have a darker brownish red coat, with some extreme chestnut horses appearing to be a dark liver brown in color. The red shade on a chestnut horse can range between a pale red and a darker reddish brown, which may appear as only dark brown, depending on the time of year and the lighting.
Most chestnut horses have the same color coat as their mane and tail, with rarely any other markings despite occasional white marks on their legs or face. However, sorrel horses can have a lighter, different-colored mane and tail to their coat. Often their mane and tail can even appear blonde.
Chestnut is also a term that can describe all red horses, whereas sorrel can only fit with lighter red colors and a lighter mane and tail. If the horse appears red but has a darker mane and tail, even if the tail and mane are so dark it appears black, this horse is considered a chestnut.

Genetically, a sorrel and a chestnut horse are the same, but some differences in color allow us to tell them apart. Unless you are 100% certain that the parents of a foal are two true chestnuts, you may not be able to know whether a foal is chestnut or sorrel, as their coat can appear grey in color until they mature.

How To Spot A True Chestnut
It is easy to confuse sorrel and chestnut horses if you do not know what to look for. Usually, you can tell whether a red horse is a chestnut by the presence of a darker brownish hue on its coat. Chestnut horses will also typically have much darker manes and tails, appearing almost black.
Chestnuts do not have a black genetic code, so when their manes and tails appear black, it is due to a rich red coloring. White or brightly colored leg and face spots are commonly found on chestnut horses.

How To Spot A True Sorrel
If you mess up and accidentally call a sorrel horse chestnut, it usually isn’t that big of a deal, as sorrel is a term for a lighter hue under the umbrella term of chestnut. All sorrel horses are chestnuts, but not all chestnut horses are sorrel.
A sorrel horse will have no black pigment, and their bodies typically have a much lighter, reddish copper-colored coat and mane. The most significant thing to look out for when trying to spot a sorrel horse is a brighter red coat with a lighter or the same-colored mane and tail. Sorrel horses will never have a darker brown or wine-colored coat; they will appear to be pure red.

The Evolution Of Different Colored Horses
While it is easy to feel suddenly overwhelmed by the different shades and coats you need to remember, there weren’t always these many variations in horse colors.
The very first horses had yellowish lighter coats with brown, darker manes, legs, and tails. This combination and color pattern allowed the horses to hide from predators, providing good camouflage.
Through the process of evolution, black and appaloosa coats started to develop in primitive herds. Geological events and climate changes led to variations in the appearance of the horses and sparked a difference in colors.
After humans began to domesticate horses and selective breeding began, there was a boom in the different variations of equine colors that were suddenly available. Chestnut and black horses were extremely popular in the copper age.
