Unknown Rare Colors and Markings

A look at horses with unknown colors and markings around the world and in a variety of different breeds.

While many of the rare markings and colors can be explained by current horse color genetics, they can’t always be visually identified (we try to be accurate with the images we use, but we make mistakes sometimes). The examples below don’t seem to fit anywhere and are a mystery to us. Until we figure them out, they will stay here where people can have a look. They are loosely lumped into two categories, colors and markings. We’ve added notes below each one with some guesses as to what they might be or things worth noticing.

Example Notes

Each image is linked to a larger version (in a new window) so you can click through and take a good look. Several of the animals have strange grey markings that look like mosaic (or maybe chimera, they are both hard to visually identify). Really they look like someone turned part of the images black and white, and some of them could be. We see this strange greying frequently enough to think they aren’t just camera/light/editing tricks and they may be a form of dominant white on wildtype bay (a disproportionate amount of them seem to be). Those pictured here don’t seem to have any characteristics that fit in with the white patterns.

Smoky white with brown eyes and dark skin
Diluted coat, white sclera, dark eyes and skin. Probably not cream, too much pigment to be grey, maybe appaloosa.
Chestnut horse with white winter coat
Chestnut with colored socks. Rabicano or appaloosa? Perhaps the winter coat version of the animals below.
White and brown horse
White/roaned patches, black ear tips and high black markings. Maybe wildtype bay.
White and brown horse
Same white/roaned patches and high black markings, also looks like wildtype bay.
Chestnut horse with white winter coat
Chimera, mosaic or strange greying pattern? Could just be a trick of the light.
White and brown horse
This view shows a bit better.
White and brown horse
Our favorite mystery of them all, Photoshop? If so it was a lot of work. Dark ear markings, grey inside, brown out. Maybe wildtype bay as well.
Bay with strange markings
Belly looks like injury marks, but the face? The legs appear to have some white striping as well.
Chestnut horse with grey face
Chestnut with a de-pigmented face. White mark on the flank, but that looks actually white, the face doesn’t.
Strange chestnut
Birthmark, mosaic or appaloosa? Marwari animals are commonly dominant white with dark eyes, but usually skin is pink.
Chestnut dilution
Another great mystery, probably a chestnut, but diluted by what? The color could be sepia, maybe mushroom?
White horse with strange spotting pattern
Leopard complex white generally radiates from the hindquarters, with colored legs. Is this a Pintaloosa? Ears are dark inside.
Strange chestnut
Just an old pony? Other than age we are unsure about this one. Dark skin and white sclera. Maybe appaloosa, but no skin mottling.
Strange chestnut
Strange coat mottling, shading, webbing or lacing. Not sure how to define it.
Strange chestnut
Almost like dun primitive markings, but no dorsal. Perhaps mealy.
Buckskin with white hairs in its mane and tail
Buckskin with white hairs in mane and tail, not mealy. Buckskin is a bay base, perhaps Gulustra’s plume?
Buckskin with white hairs in its mane and tail
Another buckskin with white mane stripe, this oe has roaning on the face, Gulustra’s plume or a white pattern?
Seal brown with flaxen mane and tail
This seal brown has a flaxen mane and tail, but dark, undiluted coat and legs look black. Maybe silver, but the color is quite warm for silver.
Horse with white stripe down its back
Unique appaloosa pattern? It’s too patchy to be roan and rabicano white radiates from the flank.
Flaxen horse with white spot on belly
These look like Black Forest Horses (which are usually flaxen). We couldn’t find any with pinto patterns, but that looks like an overo patch on the belly. The mane is almost white.
Horse with blond spot on its hindquarters
Blonde spot could be from flaxen or injury. It’s too big and pigmented to be birdcatcher and too light to be bend or (but we wouldn’t be surprised to see one).
brown and white spotted horse
We think appaloosa, with its colored socks, but there is something else there. Almost looks like birdcatcher, or maybe de-pigmentation.
Grey horse with small white spots
This is similar, but on a grey animal. Birdcatchers and grey de-pigmentation are both found in Arabians. Is that mottled skin around the eye?
Pony with strange mottling
Winter coats make classification more difficult and this one is very colorful. Not a clue.
brown horse with striping
The striping is so unique.
brown horse with striping
Easier to see on the side.
brown horse with striping
Face is mottled with a dark mask. Also no clue.
Horse with strange spotting pattern
Maybe saved the best for last. Obviously a pinto pattern at work on a black base and those spots! Pink skin, so not leopard. We would give almost anything for an image of the whole animal.
