Horse markings. How to correctly identify, name, and describe them?

Anyone who has ever stood by a horse with a passport in hand knows the feeling: you look at the white spot on its forehead and don't know if it's still a "gwiazdka" (small star) or already a "gwiazda" (large star). Or you try to describe to someone over the phone which mare you mean – and you say "the one with the white leg," even though that leg actually has a marking extending to the fetlock, and the other only has a coronet band.

Markings are one of those areas of equestrian knowledge that everyone knows superficially, but few know precisely. Meanwhile, this isn't about the horse's beauty, but about its documents and daily care. Markings are a permanent, unchanging element of a horse's identity – their identification in a passport, at competitions, and during veterinary inspections is based on them. And the pink skin underneath them requires different care than pigmented skin. So, let's clarify the terminology, explain where markings come from, and show what white hair that appears where it wasn't before indicates.

What exactly is a marking – and how does it differ from a coat color?

A marking is a congenital white spot on a non-pigmented, pink skin of a horse. Two words are crucial in this definition: congenital and non-pigmented. Markings develop before birth, during fetal development, and do not change with age – a foal born with a star on its forehead will have the identical one as a twenty-year-old. Under the white hair of the marking, the skin is devoid of pigment, meaning it's pink. This is the simplest test in practice: part the hair and check the color of the skin underneath.

It's worth distinguishing three concepts that are commonly confused in stable conversations:

• Coat color (Maść) – the color of the hair, mane, tail, and skin of the entire horse (chestnut, bay, black, gray, dun, and others). Coat color applies to the whole.
• Marking (Odmiana) – a congenital white spot on the head or legs, clearly distinct from the horse's coat color.
• Distinguishing features (Znaki szczególne) – everything that is not a marking: whorls (characteristic hair swirls), scars, striping, dark spots, breed brands, or a lighter, "glassy" eye.

This third group is often neglected, yet it is just as important for identification: a whorl on the forehead is as individual as a fingerprint, and for two horses with identical markings, it is precisely the whorl that determines which is which.

A separate category is roaning – individual gray hairs that do not form a solid spot. They are most often seen on the forehead or nasal bone and can easily be confused with a small marking. The difference is fundamental: roaning is scattered hairs on pigmented skin, while a marking is a solid white spot on pink skin.

Head markings – from roaning to a blaze

On the head, markings can be the most diverse, hence there are the most names here – from a few gray hairs on the forehead to white covering the entire front part of the head. Below are all of them in order.

Minor markings

Roaning (Siwizna) – individual gray hairs not recognized as a spot. Formally not a marking, but it is noted in the horse's description.

Fleur (Kwiatek) – a small, irregular tuft of gray hairs on the forehead. Smaller and less distinct than a star (gwiazdka).

Small star (Gwiazdka) – a small, distinct white spot on the forehead. If the spot is coin-sized or smaller, we call it a gwiazdka.

Star (Gwiazda) – a white spot on the forehead the size of an apple or larger. It can be irregular, elongated, triangular, or crescent-shaped. It's the same marking as a gwiazdka, just on a larger scale – and that's the whole difference that often causes disputes at the stable.

Stripe and its variants

Stripe (Strzałka) – a white line running from the forehead towards the nostrils. It can be straight or oblique, short or fading halfway down the nose.

Star with a stripe (Gwiazda ze strzałką) or small star with a stripe (gwiazdka ze strzałką) – a spot on the forehead connected without interruption to a line running downwards. This is recorded as a single marking.

Small star, stripe (Gwiazdka, strzałka) – two markings separated by an area of pigmented hair. The comma in the notation indicates that there is no connection between them.

Interrupted stripe (Przerywana strzałka) – a white line with a visible break in the middle.

Wide markings

Blaze (Łysina) – a white stripe running down from the forehead, significantly wider than a stripe. A narrow, regular, and wide blaze are distinguished, as well as markings extending to one or both nostrils, and left- and right-oblique blazes.

Lantern (Latarnia) – a very wide blaze covering the eye area and almost the entire front of the head. This is the most extensive head marking – and the one that requires the most attention in care, which we'll discuss in a moment.

Flesh markings and lip markings

Flesh spot (Cielista plama) – an unpigmented area between the nostrils.

Upper lip (Górna warga), lower lip (dolna warga), both lips (obie wargi) – flesh-colored markings on the lips, noted separately for each.

Frog mouth (Żabi pysk) – mottled, dark speckling on both lips.

Milky muzzle (Mleczny pysk) – the entire lower part of the muzzle in a flesh tone.

If you want to see these markings arranged in diagrams, refer to the Polish Equestrian Federation's guide to horse head markings – it's easier then to distinguish between a star and a blaze.

Leg markings – why is "sock" not enough?

On the legs, colloquial language and official language diverge the most. In the stable, we talk about socks and stockings. In the identification description, leg markings are defined by the anatomical boundary that the white reaches – and this is a much more precise system.

Going from the hoof upwards:

In addition, there are variants of the hoof's own pigmentation: white hoof and striped hoof (with vertical lighter and darker stripes).

Colloquial names are still in use and there is nothing wrong with them in conversation – it's just worth knowing what they correspond to:

• Sock (Skarpetka) – a marking ending in the cannon area, lower than a stocking.
• Stocking (Pończoszka) (also referred to as "pończocha") – a marking reaching higher, to the knee or hock. The name is in circulation, but much less common than "sock" and in many stables simply not used – so when describing a horse, it is safer to state the extent of the marking.
• Spotted coronet (Koronka nakrapiana) – white above the hoof interspersed with pigmented hairs.
• Ermine marking (Odmiana gronostajowa) – a white marking with dark speckles, resembling ermine fur.
• Zebra (Zebra) – striping on the hoof or cannon.

When recording leg markings, always start with the left front and proceed in a fixed order – left front, right front, left hind, right hind. This consistency is half the battle when later comparing the description with the horse standing in front of you.

How do markings get into the passport?

Here, markings cease to be a curiosity and become a document. According to the instruction for identification of horses and donkeys by the Polish Horse Breeders Association, the passport contains a verbal and graphic description of the coat color, markings, whorls, and distinguishing features. The diagram is filled in a strictly defined way:

• With a red pen – white markings (outline without shading), tufts of white hair, unpigmented areas, white hooves, and frosted markings.
• With a black pen – whorls (marked with a cross), scars (with an arrow), striping, dark spots, brands, and the so-called "human eye."

A fixed order of notation is also mandatory: first markings, then whorls, finally distinguishing features – separately for each body area. If the description in the passport looks like an encrypted note, it's precisely because of this: it is standardized so that two different people describe the same horse identically. The visual description is supplemented by two more things. The first is a microchip – a small transponder implanted in the horse's neck, on the left side, in the nuchal ligament, near the fourth cervical vertebra. The procedure is performed by an authorized person listed by the breeders' association. It contains a number that a reader can read in a few seconds, and since June 30, 2009, it has been mandatory for all identified horses. The second is DNA testing, performed from a hair sample from the mane or tail. This is used when the coat color cannot be unambiguously determined or when the horse's description does not match its lineage recorded in the documents.

The passport is a horse's identity document – without it, the horse cannot enter competitions, pass veterinary controls, or be transported in accordance with regulations. The article by PZJ on horse passports, "Horse passport – what is it and what is it for?", provides a good overview of the document itself. In international competitions, identification is additionally based on federation documentation – the rules are determined by FEI veterinary regulations.

In practice, it's worth doing one thing: calmly read the description of your horse's markings in its passport and compare it with the horse. Discrepancies usually emerge at the worst possible moment – during check-in at competitions.

Where do horse markings come from? Genetics without myths

Markings are not accidental. They are strongly genetically determined – studies on white markings in horses indicate a heritability above 0.5, meaning that more than half of the variability in their extent results from genes, not environmental factors.

However, there is no "star gene." A study of the Franches-Montagnes horse population published in PLOS One showed that the extent of white is determined by several genes at once, not just one. The two most important are MITF and KIT – they alone account for about a quarter of the differences between horses, and all seven detected genomic loci account for about half. The most interesting part is how they work: their effects are cumulative. The more such variants a horse inherits from its parents, the more white it will have on its head and legs.

The practical conclusion for breeders is simple and somewhat disappointing: markings cannot be planned. One can estimate the probability of a greater or lesser extent of white based on the parents, but not design a star of a specific shape.

There are also two beliefs circulating in stables that are worth correcting.

Myth one: markings say something about the horse's character. They do not. The extent of white on the head and limbs is the result of pigment cell migration during fetal development – it has no connection with temperament, willingness to work, or sensitivity to aids.

Myth two: a white hoof is weaker. This belief is so widespread that it is treated as fact. However, the quality of the hoof is determined by the ground, humidity, nutrition, and regular farrier work – not whether the hoof is light or dark. Its color alone will not tell you anything that its condition would not tell you better.

Pink skin under white hair requires different care

And here we come to the other side of the topic – one that concerns daily care, not documents.

The skin under a marking is devoid of pigment. Melanin is a natural UV filter, so unpigmented skin is much more susceptible to sunburn. Horses with a lantern, a wide blaze, and a flesh-colored muzzle are most at risk – that is, where the white covers the nose and eye area, and the hair is thin.

Symptoms to look out for during sunny months: redness, flaky skin on the nose, scabs at the edge of the marking, hypersensitivity to touch when putting on a bridle. In addition, there is photosensitization – a condition in which the skin becomes hypersensitive to the sun and reacts to it much more strongly than usual. Most often, it is caused by contact with certain plants or liver problems. Changes then appear precisely on the markings, as if someone outlined them with a marker. In this case, instead of looking for ointment, call the vet – the cause lies deeper than in the skin.

What to do in practice:

• Limit exposure during peak sunlight hours – shade in the paddock is not a luxury, it's an element of welfare.
• Protect the nose and eye area – a mask with UV filter is the simplest and most effective solution here, and it also protects the eyes from insects.
• Supplement the protective barrier with a cosmetic designed for horses, not a human product. In the range of horse equipment and care products you will find products adapted to sensitive skin.
• Watch white pasterns during the wet season. Many people notice that light pasterns irritate faster from softened mud – not in every horse, but often enough to remember. After working in such conditions, dry the legs and check under the long hairs daily. An irritation caught immediately means a few days of care, neglected – a few weeks of treatment.

Practical tips for skin protection and daily care are also well organized by the British Horse Society educational materials.

Acquired markings – white hairs that were not there before

Since markings are congenital and unchangeable, any white hair that appears during a horse's life is not a marking – it is a trace. And usually a trace of pressure, friction, or injury.

The most common areas are around the withers, the area under the saddle, the girth line, and contact points of the bridle. The mechanism is always similar: prolonged, localized pressure damages the pigment cells in the hair follicles, and the regrowing hair is white. White spots on both sides of the withers are one of the most common and unequivocal signs that the saddle is not fitting as it should.

It's worth saying it plainly: white hair under the saddle is not an embellishment, a sign of the horse's experience, or "natural wear and tear." It's an indication that something has been pressing too hard for too long. Before it appears, the horse usually signals discomfort in other ways – back tension, reluctance to be saddled, poorer gait quality, difficulty releasing its back. White hair is a later stage.

What to do about it:

1. Photograph and note – date, location, extent. This will help you see if the patch is growing.
2. Check the saddle fit. This is an examination, not a visual assessment. From the experience of Equishop saddle fitters – work supervised by Monika Zastrzeżyńska-Rychwalska – a significant portion of back problems stems from the saddle fitting the horse it was two years ago, not the horse it is today.
3. Review what's between the saddle and the horse. A washed-out, matted saddle pad doesn't cushion, and an ill-fitting one bunches up on the withers, becoming a source of pressure itself. It's worth critically examining your saddle pads once a year.
4. Don't mask the problem with a shims pad. An extra layer under an ill-fitting saddle usually makes matters worse – it acts like a thick sock in a too-tight shoe and presses even harder.

If the saddle genuinely doesn't fit, it's worth approaching the selection systematically – in the category of riding saddles, differences in gullet cut, panel placement, and seat geometry directly translate into pressure distribution on the back. Prestige Italia saddles also offer the possibility of adjustment to the horse's changing musculature, which is particularly important in progressive training.

How to describe your horse's markings? Step by step

A short, practical procedure you can perform today at the stall.

1. Position the horse in good, diffused light – not in direct sunlight, as the contrast will distort the boundaries of the markings.
2. Start with the head. Part the hair on each white patch: pink skin = marking, pigmented skin with grey hair = greying.
3. Determine the extent, not the shape. The name of a marking on a limb is derived from the anatomical boundary: heel, coronet, pastern, fetlock joint, cannon, carpus, or hock.
4. Record in a consistent order – head, then limbs starting from the left foreleg; whorls and distinctive marks separately, after the markings.
5. Compare with the passport and if there's a discrepancy, contact the breeders' association instead of correcting the document yourself.
6. Take photos – head from the front, from the side, each limb separately. This is the best documentation for sale, insurance, and in case the horse goes missing.

Most common questions about horse markings

What's the difference between a star and a blaze? Size. A star is a small patch on the forehead, a blaze is apple-sized or larger. Beyond scale, it's the same marking.

What's a stripe, and what's a blaze? A stripe is a narrow white line from the forehead towards the nostrils. A blaze is a distinctly wider stripe in the same location. A "lantern" (wide blaze) is the widest form – it covers the eye area and almost the entire front of the head.

How to name a horse's white leg? It depends on how far up the white goes. Officially, the marking is named by its anatomical boundary (coronet, pastern, half cannon, hock joint). Colloquially, "sock" is used when the marking ends at the cannon, and "stocking" when it reaches the carpus or hock joint.

Do markings change with age? No. Markings are congenital and unchangeable. If white hair appears during the horse's life, it's not a marking, but most often a sign of pressure, friction, or injury.

Are markings hereditary? Yes, and strongly so – heritability is estimated above 0.5. However, inheritance is polygenic: the MITF and KIT genes have the largest additive contribution. The specific shape of the marking cannot be planned.

Does a horse with markings require different care? Yes, in one specific aspect: the pink skin under the marking is more sensitive to UV radiation. Horses with wide blazes, broad stripes, and flesh-colored muzzles genuinely need sun protection.

Markings as part of attentive horse care

Knowledge of markings is not just theoretical knowledge for breeders. It's a skill that allows you to precisely describe your own horse, check document consistency, consciously choose sun protection, and – most importantly – recognize the moment when white hair begins to signal a problem, rather than being an element of beauty.

Horses communicate their comfort through body language and marks on their coat – our role is to read these signals early.
