What Are Bay Horses? What Makes A Horse Bay?

The word “bay” is thought to come from the Old French word “baie,” meaning “brown.”

A bay colored horse has a reddish-brown coat and dark skin with a black mane, tail, ear tips, muzzle, and legs. They can have white markings on their head and legs. Bay horses can range from golden brown, reddish brown, and purple brown. Bay coloring can be seen on horses with pinto, roan, and spotted coat patterns.

10 Things About Bay Horse Genetics

Learn all about the genetics of the bay coat color.

All horse coat colors come from one of two base pigments: red or black. Bay comes from the black base.

A bay horse must carry the right combination of the Extension gene and the Agouti gene in order to be considered genetically bay.

The Extension gene, also known as the “Red Factor,” has two alleles, E and e, that code for black or red pigments.

The Agouti gene has two alleles, A and a, and directs where black pigment is found on the horse.

The Extension gene and Agouti gene can be dominant or recessive alleles.

  • Dominant Extension Allele: “E”
  • Recessive Extension Allele: “e”
  • Dominant Agouti Allele: “A”
  • Recessive Agouti Allele: “a”

The dominant E allele lets the black color show up. Because of this, all black and bay horses have at least one copy of the E allele, making them either E/E or E/e.

The mixture of the Extension and Agouti genotypes together can be a combination of the following to produce a bay horse.

  • Bay Extension Genotype: can be either EE or Ee
  • Bay Agouti Genotype: can be either AA or Aa

If a bay horse has two copies of the same allele for a gene, “AA” or “EE,” they are homozygous for that trait . Lowercase letters mean genes that are recessive and capital letters mean genes that are dominant. They are heterozygous for the trait if they have one dominant and one recessive allele such as “Aa” or “Ee.”

You can’t tell by looking at a horse whether it is heterozygous or homozygous for the agouti or not. You need genetic testing to find out.

When different color genes are added to the genes of bay horses, other colors can be made, with bay as the base template. One such gene is a dilution gene called the “cream gene.” This causes a bay horse to be a buckskin. This gene can double dilute in horses, meaning 2 cream genes with a bay base, and the horse would be a perlino.

Bay Horse Variations

Bay Horse Color Variations

There are numerous terms used to describe the shades and characteristics of a bay coat. Some shade variations can be due to nutrition and grooming, but the majority appear to be caused by genetic characteristics that are still unknown.

Bay Color Variation Chart

Bay Color VariationCharacteristics of Color
Standard BayMedium reddish-brown color with no darker or lighter hairs.
Wild BaySimilar to a standard bay, but the black points only reach the pastern or fetlock.
Blood BayA horse with a medium blood-red tint of bay with purplish hues.
Cherry BayA lighter version of the very fiery and vibrant blood bay color.
Mahogany BayA very dark reddish brown bay similar to a deep mahogany color.
Light BayA light, washed-out, yellowish shade of bay. Similar to a lighter version of a standard bay.
Golden bayA rare golden hue bay instead of the usual bay color.
Copper BayThese horses are typical bays. This shade, though, is brighter, like a copper penny. Copper-colored horses have copper red to light copper red coats.
Dark BayDeep brown with a reddish body that looks almost black or very dark brown.
Seal Brown Near-black body, black points, mane, tail, and legs; reddish or tan around eyes, muzzle, elbow, and stifle.
Standard Bay Mare

Standard Bay

This is the color that comes to mind when you think of a bay horse. The typical bay horse coat has a reddish-brown coat with black points. It has no hair that stands out as being lighter or darker and the coat color is pretty consistent.

Wild Bay

Wild Bay

Wild bays are the shades that have the least amount of black point color. The manes and tails of wild bays are black, but the black points only go up to the pastern or fetlock. Wild bay is sometimes found with a trait called “Pangare,” which gives the underbelly and soft areas, like the area around the stifle and the nose, a pale color.

Blood Bay Horse

Blood Bay Horse

Blood bay is a darker, more intense version of the color bay. The word “blood” in the name refers to the color of the horse’s coat, which is often a deep red color.

Blood bay horses are often very striking animals, and they can be very beautiful. They are also relatively rare, which can make them even more desirable to horse lovers.

Cherry Bay

Cherry Bay

Cherry bay is another name people sometimes use for a blood bay. Although some say Cherry bay is a lighter color red than blood bay but just as vibrant and bright.

Mahogany Bay Horse

Mahogany Bay

Mahogany bay is similar to blood bay and cherry bay, but darker in color and sometimes has a purplish type of hue to the coat. Mahogany horses can sometimes be referred to as a dark bay.

Copper bay horse

Copper Bay

Most of the time, these horses are also called standard bay horses. But compared to the actual standard bay color, this one tends to be brighter, like a copper penny. Copper-colored horses have a rich, orange-red coat.

Golden bay horse also known as light bay horse

Golden Bay Horse Color and Light Bay

Light bay, also called golden bay, is the lightest shade of bay. It is less common than the darker shades.

The horse’s coat can be anywhere from a light red to a golden yellow. You can mistake them for sandy, buckskin, or dun horses.

sandy bay horse also known as buckskin

Sandy Bay

Even though a “Sandy” bay was once called that in older books about horse colors, the cream gene creates a genetic difference. Sandy bay is actually buckskin , which is not a bay color but has a bay template with a dominant cream (CCr) allele.

dark bay horse

Dark Bay Horses

The term “dark bay” is a bit ambiguous and refers to bays with darker shades of color. It can refer to dark bay, mahogany bay, black-bay, or brown (or “seal brown”). Dark bays can be so dark that they almost look black but still have some brown bay hairs mixed in. These are called black bays. A true black horse would have all black hairs.

seal brown horse

Seal Bay Horses

A dark bay color. Seal browns often have coats that are almost black, with brownish-red hairs only showing under the eyes, around the muzzle, behind the elbow, and in front of the stifle.

Dark shades of bay’s genes are still being looked into. The genetic process that makes seal brown hasn’t been found yet.

Seal brown is linked to a certain allele of Agouti. A DNA test was conducted that was supposed to find the seal brown (At) allele. However, the test was never peer-reviewed, and because it gave unreliable results, it was taken off the market.

The Most Common Bay Color Variation

The standard bay color variation is the most typical form of the bay color. It can vary from a reddish brown to a less red color. But the coat is mostly uniform.

Standard bay

Rarest Bay Color Variation

It is claimed that blood bay is the rarest bay coloration, however golden bay is also thought to be a rare color.

Blood Bay Horses

Horse Colors Often Confused With Bay

Due to their similar looks and shades of coat color, bay horses are often mistaken for other colors of horses.

Here are some coat colors that people often mistake for bay:

chestnut and bay horse

Chestnut or Sorrel

Chestnut horses resemble bay horses because of their reddish body color.

However, they don’t have black points and their manes and tails are the same as their chestnut color or a few shades lighter than their coat. Chestnuts are sometimes referred to as “sorrels.”

bay and chestnut horse

Liver Chestnut

Liver chestnuts, which are also very dark brown, can be confused with dark bay or brown horses, but a liver chestnut has a brown mane, tail, and legs and no black points.

black horse

Black

Because of their sunburned appearance when exposed to the sun, black horses are often confused with dark bay and seal brown horses.

Their coat turns a more washed-out brown tone, especially around their flanks.

Also some dark bay and seal brown horses can also appear almost black.

The hair around their eyes and muzzles is a simple way to tell a black horse from a bay horse. On these places, black horses will always have black hairs, whereas bays will have reddish-brown or light gold hairs.

buckskin horse

Buckskin

Buckskin is not bay but it does come from bay as a base color. It has a dominant cream allele which dilutes the bay color to a golden yellowish color void of any red hairs.

You can get confused with the buckskin because it also has black points like the bay. And can sometimes look like a golden or light bay.

If you are unsure you will want to do genetic testing to find out.

Dun horse

Dun

Dun can be confused with bay the same way that buckskin can be confused. A bay dun can range in shades as well and sometimes a dun can look very similar to a light bay or buckskin color.

A bay dun also has bay as a base with an added dun gene. A dun will have a stripe down the back, wisps of light colored hair in the mane and tail along the base of the mane and tail and can have faint strips on the legs and forehead.

Coat Colors In The Bay-Family

The influence of extra equine coat color genes on a bay base coat template has the effect of transforming the basic color into a variety of colors and patterns.

Chart For Colors In The Bay-Family

Bay Family Color Characteristics of Color
Sooty BayA sooty modifier gene that causes darker areas on bay coat usually around the topline of the horse. A dark bay coloring.
Pangaré Bay Pangaré is a modifier gene that lighten hairs around the legs, belly, muzzle and can lighten the whole coat color as well.
BuckskinThe cream dilution gene lightens the red parts of the coat to a yellow or golden color.
PerlinoTwo cream alleles on a bay has a creamy pinkish or reddish hue similar to the cremello. The skin is a pinkish and the black turns to a brownish color sometimes lighter similar to the rest of the coat.
Silver BayThe Silver dilution gene causes a dappling affect under the coat and turns the black mane and tail into a white silvertype color. Other black points can become more diluted and look browner.
Bay DunDun dilution gene on a bay lightens the coat to a yellow similar to buckskin., but the bay dun will have primitive markings along with the color.
Bay RoanThese horses are typical bays. This shade, though, is brighter, like a copper penny. Copper-colored horses have orange-red coats.
Rose GreyA pinkish reddish grey coloring caused by a bay horse turning grey from the grey modifier gene. This is typical in the younger years of the horse, but the foal is born bay to start.
Bay Pinto The coat consists of large and small patches of white on a bay base.
Bay LeopardSpotted pattern on a bay base. Bay horses tend to have a pattern that looks like a spotted blanket.
Bay RabicanoRabicano, sometimes called white ticking, is a horse coat color defined by restricted roaning in a particular pattern: its most simplest form is shown by white hairs at the tip of a horse’s tail, then at the flank, then other regions of the body.

Sooty Bay

Bay + Sooty= Sooty Bay

Sooty is a modifier gene.

Many dark bays are caused by the sooty gene. Horses that don’t have any sooty traits on them are called “clear-coated.”

Sooty is probably in every breed of horse, and many horses show some signs of it.  

Bay horses with the Sooty trait have dark hairs and spots on the top of their bodies. This dark topline may look like a rather broad dorsal stripe, as is seen in dun horses.

This is called “countershading,” because the parts of the horse that should get lighter because of the sun are instead darkened. It is thought that this will throw off predators.

Pangare Bay

Pangaré Bay Horse Color

Bay + Pangaré= Pangaré Bay

Pangaré is a modifier gene.

Pangaré, also called the “mealy effect,” is common in draft horses and ponies, but it is much less common in sport horses. It can be seen on bay and chestnut horses and the mealy affect is also seen in donkeys, but it may be caused by a different set of genes.

It remains unclear clear if Pangaré is caused by one gene or more, or if it is a recessive trait or a dominant trait.

Usually, it makes the area above the muzzle, the sides, and the belly lighter, but it can also make the whole coat lighter. It might have started out as a way to blend in with the background.

The genes for Pangaré are still not known, and there is no genetic test for it.

Buckskin Horse Color

Bay + Cream= Buckskin

Cream is a dilution gene.

A buckskin horse is made when a single copy of the cream allele, either CR or CCR, is mixed with a bay horse. The red bay’s coat turns yellow or gold, but the points (the mane, tail, lower legs, and ear tips) stay dark.

If the horse’s coat is seal brown, the coat will get a lot darker. The hairs range in color from yellow to almost black. The hairs on the belly and nose are the lightest. This color is also called brown buckskin or smoky buckskin.

When there aren’t many yellow hairs, it looks a lot like a standard brown color.

Perlino Horse Color

Bay+ 2 Cream= Perlino

Perlino has a double cream dilution.

It has a light, creamy coat, just like a cremello. The two cream alleles are to blame for this. Most of the time, though, the mane and tail are darker than the body and have a more reddish color.

There are, however, perlinos with hairs so light and long that they can’t be seen. Like a cremello, a perlino’s skin turns pink and its eyes are a light blue color.

Amber Champagne foal

Amber Champagne Horse Color

Bay+ Champagne= Amber Champagne

Champagne is a dilution gene.

A gold champagne looks like it was made by diluting the red coat of a bay horse to a metallic golden shade, but the mane, tail, and legs of the horse remain the typical champagne’s chocolate brown. There may not be much difference between the legs and the rest of the body. In fact, the brown may be almost nonexistent on the legs.

Amber champagnes look a lot like buckskins, but the skin on a buckskin is dark, while the skin on an amber champagne is more of a light pink. The  coat also has a more metallic sheen.

The seal brown form is known as sable champagne, and it may be difficult to differentiate from amber and classic champagne.

Silver Bay Horse Color

Bay+ Silver= Silver Bay or Silver Seal Brown

The silver dilution is not a well known dilution, yet it has been seen in a handful of breeds.

It is a common trait in the Rocky Mountain Horse for example. The popular name is silver or silver dapple, abbreviated as Z. Other terms used with Silver horses include “Taffy” and “Chocolate.”

The manes and tails of black and bay horses are diluted by silver. It may also have an impact on the lower leg’s black, occasionally diluting it or causing diluted regions. The impression is frequently more pronounced in younger horses since the mane and tail darken with age, often to the point where they look nearly unadulterated.

Silver foals have striped hooves and white eye lashes, however these traits may fade as the horse grows older. Both may be created by other colors, therefore existence is not proof in and of itself.

Bay Dun Mustang

Bay Dun

Bay+ Dun= Bay Dun

Dun is a dilution gene.

Brunblakk is the Norwegian term for bay dun, and is the most common color in the fjord horse.

Bay dun, is often confused with red dun, as well as the buckskin color.

Dun is likely one of the oldest dilutions, since many people think it was the first color of horses. It dilutes the red and black pigment, but it doesn’t change everything.

This is what causes the so-called “primitive markings,”:

  • dorsal stripe
  • leg barring
  • shoulder and sometimes neck stripes or shadows
  • darker ear tips
  • frosting in the mane and tail
  • a dark face mask
  • mottling on the upper leg
  • cobwebs on the forehead
  • brindling

The horse doesn’t always have all of these at the same time. Also, the coat is made a little bit lighter and less bright, which makes the darker markings stand out more.

Bay Roan quarter horse

Bay Roan Horse Color

Bay+ Roan= Bay Roan

Roan is a white pattern gene.

The body of a roan horse has an even mix of colored and white hairs, while the head, lower legs , mane, and tail (called “points”) are mostly one solid color.

The color of a bay roan horse’s coat is bay mixed with white hairs in an even way. There are a little to no white hairs on the head, legs, mane, and tail.

The roan pattern is passed down by dominant inheritance and can be found in many breeds of horse. True roan is always there when a foal is born, but it may not be easy to see until the foal is older.

Roan is known as  a dominant trait represented by the Rn allele. Dominantly inherited traits are handed down to each generation, which means that two non-roan parents cannot create roan offspring.

Bay Pinto

Bay+ Pinto= Bay Pinto

Pinto is a white pattern gene.

Bay pintos are bay horses that have one or more white-spot genes, such as tobiano, frame overo, splashed white, and so on. The pattern has nothing to do with if the horse is bay or not. Pinto horses can also have a base coat color of bay with white spots on top. People sometimes call bay pintos “skewbald” or “tricolor.” 

Even though sabino is a pinto color pattern, certain horses with highly pronounced white markings or mild body spotting may be classified as “bay” by their owners, especially in breed registries that do not offer a category for pinto.

Bay Leopard

Bay+ Leopard= Bay Leopard

Leopard is a white pattern gene.

The leopard (Lp) gene or gene complex, found in Appaloosas and other horse breeds, is also present in Bay Leopards. As a result, this gene creates a spotted coat, white eye sclera, and striped hooves.

Bay Rabicano

Check out this image of a Bay Rabicano.

Bay+ Rabicano = Bay Rabicano

Rabicano is a white pattern gene.

Some bay horses may have the rabicano gene, which makes some parts of the body have a faint roan or makes some white or cream hairs grow in the mane or tail, giving the horse a “skunk” look. Most rabicano-carrying bays are classified as bays or bay roans.

bay foal turning grey

Rose Grey Horse Color

Bay+ Grey= Rose Grey & Eventually Full White Grey

Grey is a modifier gene.

A bay horse with the grey modifier will be born bay and start to lighten as they get older. White hairs will begin to intersperse through the coat. This can happen faster or slower depending on the horse.

Sometimes grey horses can be confused with roans when they are younger and growing more white hairs.

However a roan is born with the peppered coloring , where as a grey begins to develop the white hairs as they grow. A bay horse with the grey gene ends up having a rose grey color until their coat begins to white out. The coat will look to have a pinkish or reddish tint to it.

When the horse gets older, their coat will eventually be white or even flea-bitten. Although flea-bitten horses typically come from a chestnut base coat.

Bay Horses In Different Horse Breeds

There are many horse breeds that come in the color bay. In some breeds, bay is a very common color more so than other breeds. There’s even a breed of horse that is exclusively bay. There are also a small few horse breeds that don’t come in the color bay at all.

suffolk punch doesn't come in bay

Suffolk Punch 

Suffolk Punch horses are a beautiful and unique breed that is known for their chestnut or sorrel coloration. They lack the black gene, which is required for the bay color. 

Purebred Friesian doesn't come in the color bay

The Haflinger is a beautiful horse breed that is dominantly chestnut in color with a flaxen mane and tail. They do not come in the coat color bay.

7 Fun Facts About Bay Horses

Bay is the most popular horse coat color. They are even considered the standard horse color. A bay horse can be found in practically any discipline, including racing, western and English competition, and pleasure riding.

There are only two basic pigments that make up all the colors of horses, which are red and black. Bay comes from the pigment black, with a dominant Agouti gene pushing back the black to the points of the horse.

Bay is one of the three basic types of horse coat colors, which are bay, chestnut, and black. They can be thought of as templates to which other genes can be added to make other colors.

The pigment of a bay horse’s coat, regardless of hue, is rich and thoroughly saturated. If properly cared for, this makes bays especially glossy in the sun. Some bay horses have dappling, which is created by textured, concentric rings within the coat. Dapples on a bay horse indicate good condition and care, yet many well-cared-for horses never dapple. Dappling may also be genetic.

Red areas of a bay coat have a two-toned hair shaft, which, if clipped short, may cause the horse to appear many shades lighter, a dull orange-gold, almost like a dun. As the hair grows, it will darken again. This effect is linked to the genetics that create red coloration in horses, but not in body-clipped darker bays because there is less red in the hair shaft.

Except for the skin under white markings, which is pink, bay horses have black skin and dark eyes. Knowing this can help you tell the difference between a bay horse with white markings and a horse that looks like a bay but isn’t.

It is thought that the non-dun 1 allele is responsible for the faint dorsal stripe that appears on some bay horses.

Famous Bay Horses

Here are some bay horses who are famous in history, racing and as sport horses.

FAQ’s About Bay Horses

Can a bay horse have a black foal?

Yes. The number of times a bay gives its color to its young varies. Two bay horses that are heterozygous for E (Ee x Ee) have a 25% chance of having a chestnut foal. In the same way, bay horses that are heterozygous for A (Aa x Aa) can have a black foal.

Can a bay horse be homozygous black?

 Yes. The final color of a horse is the result of the interaction of 11 largely separate processes. Multiple alleles influence coat color, hence homozygous black may or may not be black in color. Depending on the genetics, this horse might be bay, grullo, smokey black, or even gray.

Can bay horses have dapples?

Yes they can. It is both genetic and environmental in nature. There are horses who will have dapples regardless of their condition, and horses that will never dapple even if they are in perfect health. Temperature is one environmental component considered to impact color to some extent, so the lengthy, chilly spring might have had a role.

Can bay horses have dorsal stripe?

Bays can have a dark stripe but don’t have a true dorsal stripe, it would just be counter-shading that looks like one. Although it’s not clear and the edges aren’t sharp. A real dorsal stripe looks like it was made with a marker.

What is a dark brown horse called?

A dark brown horse is an ambiguous term. Depending on the traits and specific coloring, it can be a dark bay, mahogany bay, seal brown or liver chestnut.

What are the different shades of bay horses?

These are 12 shades of bay that can be named. Although it has been argued that some of the shades are the same color just with different names. The different shades of bay include standard bay, wild bay, blood bay, mahogany bay, cherry bay, copper bay, golden bay, sandy bay, light bay, sooty bay, dark bay, and seal bay/seal brown.

Are all thoroughbreds bay?

Not all thoroughbreds are bay. However bay is a very popular color in the thoroughbred breed. Thoroughbreds come in many other colors as well, such as black, chestnut, grey and more.

Can a bay horse carry a cream gene?

No a bay horse cannot carry the cream gene. The cream gene is dominant and you would see it in the horses coloring. One cream allele with a bay would create a buckskin and two cream alleles with a bay would create a perlino.

Can bay horses turn grey?

If the horse is bay with a grey modifying gene then yes. The horse will be born bay and gradually turn grey.

Can bay horses have brown manes?

No bay horses always have black manes.

Do all bay horses have black legs?

Yes, all bay horses have black legs.

What type of horse is a bay?

Bay is not a type of horse. Bay is one of the three basic colors of horses.

What is the difference between bay horse and chestnut?
