Buckskin and dun-colored horses can look very similar. It’s very common for people to get the two colors confused. However, there are distinct differences, some genetic and some you can spot visually.
Buckskins have yellow colored bodies with a black mane and tail and black points, like on a bay horse. Duns range in colors from reddish to yellow to mouse grey with frost on mane and tail as well as primitive markings such as a dorsal stripe, shoulder blade stripes, webbing on their forehead, and stripes on the legs.
This is just a basic summary of the visual difference between buckskin and dun coat colors. Now let’s go more into the genetics behind these coat colors, the variations you can find in each of these colors, other colors that can commonly be confused with dun or buckskin and answer any questions you may have on the topic of dun and buckskin horses.
10 Genetic Facts About Buckskin & Dun Horses
- Buckskins are created through the cream gene, on a bay base color. Also, the bay base is technically black with the agouti gene. The agouti gene pushes the black color to the mane, tail, and black points of the horse leaving the bay color which can vary in shades. This stays and only the bay color turns to a yellow gold color.
- Duns are created with the dun gene, which can be on any base color.
- Both the cream and dun genes dilute the color of the horse’s base coat. The cream turns reddish colors to a yellow or gold-like color. The dun just lightens the horse’s coat color and adds dun markings.
- The cream gene only affects red base color and not black when one is present. When two cream genes are present red and black base colors are effected. The cream gene can lighten the skin, coat, and eyes.
- The dun gene affects both red and black-based colors.
- The dun gene commonly leaves the mane, tail, and some other areas of the body the original undiluted base coat color. Although it is also common for the mane and tail to have frosting which are light-colored hairs on either side of the mane and tail.
- Buckskin horses can also have the dun gene, they are called a dunskin. This means the horse has a base coat bay with one cream gene and one dun gene.
- Buckskin horses can have a dorsal stripe and not be dun. Dorsal striping alone does not mean the horse is dun. There are two types of non-dun horses known as non-dun 1 and non-dun 2. Non-dun 1 has no color dilution but can have primitive markings. Non-dun 2 has no color dilution and no primitive markings.
- Dun gene is a dominant gene. If one of the parents is dun then the foal will inherit the dun gene.
- Today to confirm if a horse is dun DNA testing can be done, examining the horses pedigree, and checking for the visual signs the horse is dun, such as primitive markings, dorsal stripe, and color dilution.
Buckskin Color Variations
Buckskins always have a black mane and tail, however, the shade of buckskin can vary. A dorsal stripe which is commonly seen as a dun trait can in fact still be a buckskin if it is countershading or the horse is a non-dun 1. Countershading is seen on adult horses of most colors but is more common in foals and usually fades out.
“Countershading markings that can closely resemble dun are false dorsals, shoulder bars, and stripes or mottling on the legs. A true dun dorsal will almost always be visible well into the tail while countershaded dorsals will not.”brindlehorses.com
The different coat color variations of buckskin:
The Standard Buckskin
This is the most commonly thought of color when it comes to buckskin. The shade can vary slightly but it is most similar to the color of tanned deerskin.
Buttermilk buckskin is the lightest shade of buckskin, a very light creamy yellow color, which really contrasts against the black mane, tail and black points.
The golden buckskin looks similar to the standard buckskin but is slightly darker in the neck and shoulder and back areas.
Sooty Buckskin looks as if soot was dumped on top of the horse. The top of the coat is darker while the bottom of the coat is lighter giving it the look. The coat is not as diluted as the other buckskin variations.
I have seen two examples of a silver buckskin. The true silver buckskin is a bay horse with the cream gene and the silver dapple gene. The horse’s body has the gold yellow body with a white or silver looking mane and tail. Check out a photo of this Silver Buckskin Tennessee Walking Horse.
Then there is the silver buckskin that has a black mane and tail black points and the coloring of their coat is anywhere from a very light buckskin with silverish tint to much more prominent silver coloring. These are not true silver buckskins because they don’t have the silver dapple gene.
Other Buckskin Variations
There are other buckskin variations with buckskin as a base with another gene. The silver buckskin with the silver dapple gene for example.
Other variations with buckskin as a base coat include:
- Buckskin Tobiano
- Buckskin Overo
- Buckskin Tovero
- Buckskin Roan
- Dunskin Roan
Dun Color Variations
The most common dun coat color looks like a buckskin horse, which is why so many people confuse buckskin with dun or vice versa. A dun horse can come in several different colors and have certain characteristics known as the primitive markings.
Dun Horse Primitive Markings
A dorsal stripe is a darker colored line that runs through the horses mane, down the back, through the tail. The stripe does not fade away. The color of the dorsal stripe is of the horse’s base coat, but on a bay it can be black or reddish. That’s because the bay color is originally black with the agouti gene.
Sometimes on a dun, the face will be darker which is sometimes called a face mask. Subtle stripes on the horse’s forehead are also common, similar to a tiger or brindle but more faint is called cobwebbing.
These are horizontal stripes on the horse’s legs that are usually faint. These are usually found on the back of the forelegs, above the knees and hocks as well. They are also sometimes called zebra bars.
Known as the transverse stripe. This is another trait sometimes found in dun horses and also donkeys. The shoulder stripe is near the horse’s withers and is a line perpendicular to the dorsal stripe. Looking at it from an aerial view, it would almost look like a cross.
Mane And Tail Frosting
This is the hairs on the edges on both sides of the tail and mane. The color is lighter making it look frosted. It can be just a little bit and not really noticeable or a lot of frost and very noticeable.
Dark Ears Tips
The tip or rim of the ears are often darker and similar in color to the horse’s dorsal stripe.
Red dun is with base coat chestnut or red. The coat is much lighter than the normal chestnut colors. The color almost looks like a chestnut coat that has a full body clip. The dorsal stripe is usually a brighter chestnut.
Black dun is more commonly known as grulla or grullo. The dun gene lightens the black to an almost blue or steel grey. The face usually has a dark mask along with the other dun characteristics.
Bay dun is the color commonly confused with buckskin horses. It is a yellowish color. The Dun gene lightens the bay color and turns the red more yellow. There are varying degrees depending on the horse. Some look slightly more reddish bay and some more yellow.
A buckskin dun is known as a dunskin. The buckskin has the yellow buckskin coat and the black mane usually with some frost on the mane and tail. Then the other dun characteristics.
A palomino dun is known as a dunalino. The palomino has the golden coat with the platinum blonde almost white mane and then the characteristics of the dun.
