Blue Roan Horses
There are few sights more breathtaking and stunning to see than a blue roan horse. A majestic animal with a coat that appears almost blue, there is little wonder that in times gone by they were once considered mythical beings.
While horses can come in many colours and with many different markings, it is impossible to find a real blue horse. However, the blue roan is arguably one of the rarest colours that you will ever see and it is certainly one of the most unique. A blue roan is a horse which has a black base colour with a mixture of white hairs evenly mixed across the body which gives the “blue” appearance while the head and legs remain of solid colour, also black.
Blue Roan Genetics
The genetic make-up of blue roans is as fascinating as it is complex, but before we delve into it, it’s important to note that sometimes there are horses that appear to be “roan” in their colouring, but they are not actually a true roan. This could be because they have slight variations in their base colours and have some white hairs mingled in, or due to their markings, or it could also be because the horse is a grey who’s colour is still developing (grey horses are born a solid colour and lighten over time, thus sometimes appearing as roan). In particular, the Rabicano colour pattern is often mistaken for being a roan, as is the Sabino colouring. However, the Rabicano colouring has white hair mainly around the tail and flanks, unlike the roan where the white hairs are mixed evenly across the body.
A horse must have two roan parents in order to be a true roan and the roan gene itself is a dominant gene, symbolized by the “Rn” allele. Even if a true roan horse appears to have a parent who is not roan, the gene must be present in the parent and they will have some roan colour in them, even if it is masked by other colours or markings, making them appear as though they are not roan.
The three main base colours of horses are black, chestnut, and bay. Black genes are symbolised by “E”, chestnut by “e” and bay by “E” + “A”, and simplified these genes must be paired with the roan gene “Rn” to produce roans (blue, red, and bay roans respectively).
If we look deeper into the genetics of roans and particularly blue roan horses, then the “Agouti” gene (A) determines where the black colouring will be on a horse. If it is recessive (aa) then the horse will be black on it’s legs and the body, but if the gene is dominant (Aa or AA) then the horse will be bay if paired with a dominant black gene (EE or Ee) to produce black legs and a red body, or chestnut if paired with recessive black gene (ee), ie no black, and all of these will produce roans if combined with the roan gene (Rn).
Therefore, to get a blue roan the horse must carry the dominant black gene “E” for the base colour and the roan gene “Rn”. The particular circumstances which the genetic make-up of the blue roan needs makes it very difficult to intentionally breed a horse that is blue roan. It is possible but in most circumstances you would need to know the exact DNA make-up of both potential parents, which is why, more often than not, blue roans are born by pure chance.
Blue Roan Horse Facts
l When a blue roan is born they appear to be a solid colour - usually black. However, the roan is present but it is covered by the initial foal coat and the white hairs only appear once they begin to lose it. The roan colouring starts to show by the time they are two to three months old and will usually be fully visible by the time they are a year old.
l Due to the longer hair of the winter coat, blue roans usually appear darker in winter.
l If a blue roan has a cut or scrape which scars then the hair will grow back black over it without any white hairs, therefore creating a black mark in their roan colouring. This is a contrast to most other colours which would usually scar white.
l Blue roan horses are often mistaken as grey by people unfamiliar with the colouring.
l The roan gene does not exist in Arabian horses so you will never get a true blue roan Arab, or any Arabian horse which is a true roan for that matter. However, the Rabicano colouring is present in Arabs and as such they are often mistaken for roan Arab horses.
l Roan horses have been much revered throughout history and in Shakespeare’s play Richard II King Richard was portrayed as riding a roan horse, and Shakespeare also mentioned roan horses in several of his other plays.
l Blue Valentine was a blue roan stallion who was born in 1956 and became famous on the rodeo circuits, excelling at roping, cutting, and barrel racing, along with regular ranch work. He became a legendary sire and died in 1980 after suffering from colic.
l Dapples are reversed on blue roans - instead of having dark dapples, blue roans have light dapples which appear as lighter circles on their coat, therefore reversed.
Horse Breeds with the Blue Roan Colour
American Quarter Horse
As blue roan is a colouring and not a breed, there are many breeds of horse which can be blue roan. Blue roan is more common in some breeds than others and is found most often in many breeds which originated in North America, particularly in the American Quarter Horse.
Bred for their power and endurance and famous for their abilities on working ranches and in rodeos and on the barrel racing circuits, there have been several blue roan horses over the years, some of which have proved exceptionally talented at their jobs and gone on to be prolific breeders, passing on those traits (and the colour at times) to their offspring. The blue roan is a recognized colour of the Quarter Horse by the American Quarter Horse Association.
Standardbred
Used predominately in harness racing, the Standardbred is another breed which has the blue roan colour, although it is not seen as frequently as in the American Quarter Horse. The Standardbred is a breed that was developed in North America, although it’s origins go back to Thoroughbreds, Morgan, and Hackney horses so it’s possible that the blue roan gene evolved from those early influences. A mostly calm breed of horse, the Standardbred makes for a good riding horse with plenty of athletic ability, although some retraining may be required if the horse had raced before beginning it’s ridden career.
Percheron
The Percheron is a breed of draught horse which originated in France. It is one of the oldest heavy draught breeds in the world and it’s origins can be traced back to around AD 800. The modern Percheron was used by the British Army during the First World War to pull the guns due to their strength and calm nature. The Percheron is famed for it’s muscular stature, good temperament, and versatility.
Welsh Pony
The blue roan is more common in the Welsh Pony and Cob (all four sections - A, B, C & D) than in some other breeds of horse. Originating in Wales, early types of Welsh ponies and cobs existed before 1600 BC, although it is thought that, like the Standardbred, they were influenced by Morgan and Hackney horses. They are a versatile breed which, due to the different breed sections and heights, are suitable for children right up to adults. They have had a variety of uses over the years, from pit ponies to working on farms, and latterly as riding and show ponies. They have an excellent temperament which makes them suitable for children and they have smart movements which mean they usually excel in the show ring.
Hackney
With both the Standardbred and the Welsh Pony having their origins in the Hackney breed, it could be suggested that those breeds have received their blue roan genes from the Hackney itself, and indeed, blue roans are found within the breed. Developed in the United Kingdom, the Hackney has a high stepping action and the ability to trot at great speeds. They are perhaps one of the smartest moving horses around and are well known as excellent driving horses - their showy action making them highly desirable horses to pull carriages with, particularly throughout the nineteenth century amongst the more well-to-do of society.
Morgan
The Morgan is another breed which seems to have had an influence in the origins of the blue roan gene, and indeed there have been several well known blue roans within the breed, including a popular dressage horse called Caduceus Herod. The Morgan is one of the earliest breeds of horse to be developed in America and has had many jobs throughout the years. They have been successful in harness racing, as coach horses, and were also used as Cavalry horses in the American Civil War. In more modern times they are successful across a range of disciplines, including dressage and show jumping.
Paso Fino
The Paso Fino originated in Puerto Rico and blue roan is a recognised colour of the breed. The Paso Fino is a particularly unique breed of horse as they are a “gaited” breed that has different gaits to usual horses which are unique to it’s own breed. They have the classic fino which is a collected show gait. Their paso corto gait is the equivalent of a trot but is much smoother. The paso largo is a much faster gait, more like a canter or a slow gallop. Paso Fino’s are a popular breed across America nowadays and they are used in a wide variety of disciplines.
Shetland Pony
Originating in the Shetland Isles, Shetland ponies are famed for their strength and hardiness and make fantastic children’s ponies due to their calm and affectionate nature. While there is a vast array of colours and markings of Shetland ponies, the blue roan is a recognised colour by the Shetland Pony Society and it is not that rare to find a Shetland that is blue roan, although it would be harder to determine the origins of the true blue roan genetics in Shetland ponies.
FAQ’s
Do blue roan horses turn white?
No, unlike grey horses which get progressively lighter as they get older, a blue roan horse remains the same colour throughout it’s life, although they can appear darker in the winter due to the longer hair of the winter coat.
What is a true blue roan horse?
A true blue roan horse is a horse which has a black base colour on it’s body with white hair mixed in evenly throughout it’s body, giving the appearance of a blue colour. The head and legs are black. The true blue roan must also be from parents who were both roans.
Is a blue roan horse rare?
While not rare as such, the blue roan horse is one of the least common colours found in horses and is certainly difficult to intentionally breed.
Are blue roan horses expensive?
Unless someone is buying it specifically for it’s colouring or with the intention of attempting to breed another blue roan, then blue roan horses should not be more expensive than other horses of the same breed or calibre.
Are horses born blue roan?
Yes, a horse that is a true blue roan will be always born roan although they will appear to be black until they begin to lose their foal coat. By the time the foal is two months old the roan colouring is usually visible to some extent.
