Every ROX horse wears one coat, drawn at mint and never changed. It never affects speed — it affects how much everyone else wants your horse.

A horse's home planet decides which family it draws from. That one rule explains the whole palette: horses that stayed on Kepler-442b kept their natural coats, and horses that teleported out took on the colour of where they landed. It also survives breeding — a Kepler foal is born natural, and never turns Neptune blue.

The palette is closed. Breeding never invents a colour: a foal inherits from a parent or, on the rare mutation, re-rolls one of the published colours below. These are the only coats there will ever be.

A note on migrated ZED horses. Every coat on this page belongs to a ROX horse. A migrated ZED horse keeps its own coat — "Anti-Flash White", and the rest of ZED's palette — and those colours are not listed here and are not part of the ROX palette. They are a different species and their coats are their own.

What a mixed foal wears is genuinely not decided yet. Rather than invent an answer and quietly correct it later, we would rather say plainly that it is open: cross-species breeding is not switched on, and when it is, the colours a hybrid can wear will be published here first. Nothing above changes when that happens — the ROX palette is still closed, and still these coats.

Kepler-442b

The first world, and the only one whose horses never changed colour. Every Kepler coat is a real horse coat — bay, sorrel, dun, gray, cremello — with the white markings real horses carry: blazes, socks and pinto patches.

Kepler coats are worn only by Hyperions. That is what makes the elite tier recognisable on sight: among seven planets of invented colour, a Hyperion is the one that looks like an actual horse. No amount of breeding moves these coats onto another bloodline.

The King and the Queen

Two coats will never be minted and never be born: pure Black and pure White — the natural black and the natural white of Kepler, worn by exactly two horses, the founding DN0 pair. They are the purest horses in the game, and they wear the plainest coats.

Both stand for sale on the ROX marketplace, in dollars: the Black King at $3,000,000, and the White Queen at $5,000,000. The royal stud stands with the King, whose fee is published on his stud listing. Until they are bought, they race and stand for the house. If you ever see a white or black horse on a track, you are looking at royalty. There is no third.

The originals · all 50, Hyperion only

These are not examples. These are the 50 original Hyperions, every one of them, exactly as it will be sold — tokens 3 to 52, the DN1 and DN2 ranks. The collection has since gained a fourth rung: 50 more Hyperions at DN3, which are not pictured here. With the King and the Queen that makes 102. Five Kepler coats across ten to twelve marking states, and no two are alike: where two horses share a coat and a marking, their mane and eye colour differ. On a racecourse you can tell every one of them apart, which is the point of an elite tier.

Markings & patterns · 96 masks

A coat is the colour. A marking is what goes on top of it, and the two are independent — any marking can appear on any coat. A horse wears at most two at once, which gives 186 pattern states in total: 96 single markings, 89 pairs, and one clean coat.

Markings are white — with one exception, and it is a deliberate one. A coloured marking arrives in two ways: through breeding, or on a crown-tier genesis horse. The 50 Hyperion DN3 horses each wear a body splash in a second Kepler colour, and that splash is the rung showing: it is the only place in the collection where colour sits on colour without a pedigree behind it. Anywhere else, a coloured spot means somebody bred for it.

Pure blood shows as one colour. The King and Queen are solid black and solid white — the purest horses in the game wear the plainest coats. Body patterns signal diluted blood, so no genesis horse on a colour planet carries one. Most Hyperions carry none either — and where one does appear it is a splash or a patch, never a pinto, a leopard or a blanket. Every generation you breed away from the crown, broken colour becomes more likely.

Face and leg markings are different: a blaze or a pair of socks is an ordinary breed characteristic that says nothing about ancestry, and any horse may carry them.

The same markings, on a coat you cannot buy

Every example above sits on a Kepler natural, because that is all the genesis mint contains. Breeding puts the same markings on invented colour, in a second colour drawn from the other parent — and that is a horse that exists only because somebody made it.

What breeding does to a coat

Everything above is the genesis mint — the horses that exist because we made them. Every horse after that comes from breeding, and its coat is decided by its parents and its blood, not by us.

Blood decides how broken the colour is

A horse's coat tells you what it is. The purer the blood, the more solid the colour — the King and Queen are pure black and pure white, and no horse in the game is purer than they are. As blood dilutes down the generations, colour breaks up into patches.

So a foal that rolls up toward Hyperion tends toward a cleaner, more solid coat. A foal that settles lower carries more broken colour: pinto patches, leopard spotting, roan ticking, a blanket over the hindquarters. You can read a horse's approximate breeding from across a paddock, which is exactly how it works with real bloodstock.

Face and leg markings are the exception. A blaze, a star, a pair of socks — these are ordinary breed characteristics and say nothing about ancestry. Any horse can carry them at any bloodline.

Colour in a marking can only be bred

At genesis every marking is white. Nothing you can buy in the mint has a coloured spot.

Breeding is the only way a marking takes on colour, drawn from what the parents carry. That is why a horse with gold patches on a blue coat cannot be bought at any price — somebody bred for it, across generations, and the pedigree proves it.

How large the space actually is

Each coat gene — base colour, pattern, mane, eyes, and the colour of each marking — is inherited separately, a coin flip between the parents. The palette they draw from is closed and fixed, and it is worth being precise about its size rather than impressive about it:

Marking designs (the body art itself)	96
Pattern states — 1 clean, 96 singles, 89 pairs	186
Mintable coat colours	78
Mane colours · eye colours	6 · 5

Everything beyond those 186 pattern states is recolouring: the same body art in a different colour. That is real variation — a gold blaze on a blue coat is not a white blaze on a bay — but it is not new artwork, and we are not going to pretend otherwise.

Counting colourways, a horse with white markings can look 435,240 different ways. Once a marking can carry its own inherited colour, drawn from a palette that excludes the coat's own, the combinations reach 1,252,073,160.

Read that second number for what it is: a combination count, not a gallery. It is the ceiling of what the system can express, not a promise of a billion distinguishable horses. The honest headline is the one above — 96 marking designs, 186 patterns, 78 coats.

The palette itself never grows. Breeding invents no new colour: every coat a foal can wear is already on this page. Super Rare colours can never arrive by mutation, only by inheritance — their population can hold or shrink, never expand.

Three steps, and you cannot skip one

How a horse looks is decided by how many colours its line has absorbed, and a line absorbs them one at a time. This is the whole of it:

One colour — a matched pair breeds true. Red on red gives red. Blue on blue gives blue. Always, with no roll and no exception. The markings are there, but they are the same colour as the coat, so the horse reads as solid. That guarantee is what makes line-breeding worth doing: you know exactly what you are getting.

Two colours — the second parent shows. Put a red mare to a violet stallion and the foal carries both. Sometimes it comes out solid like its mother, sometimes solid like its father, and sometimes it wears one as its coat and the other as its markings. That third outcome is the two-colour horse: gold spots on a blue coat, and the spots name the other parent.

Three colours — the far end. Take a two-colour horse and breed it to a third colour, and the line is now carrying more than a coat can show plainly. That is when the body patterns arrive — brindle striping, marbling, belted bodies, the coats no genesis horse wears. They are not handed out and they cannot be bought. They are what a third colour entering a pedigree looks like.

So a solid horse tells you its parents matched. A two-tone horse tells you they did not. A brindle tells you somebody kept going. Nothing about the coat is decoration — it is the record.

A foal's bloodline is drawn against the published odds at the moment the cover is booked — a fixed table, set before anyone pays, with structural limits no roll can cross. The appearance rolls above follow the published inheritance rules from the parents' own coats.

Twenty of the combinations

None of these can be bought. Every one has to be bred. They are drawn from the 186 pattern states and the colour palette above — the combination space runs to 1,252,073,160, though what makes each of these distinctive is the body art and the colours it carries, not the size of the number. Here are twenty.

Two colours — what breeding does with an inherited palette

These are step two: one parent's colour as the coat, the other's as the markings. A marking takes its colour from what the parents carry. Gold spots on a blue coat means a Saturn horse somewhere in the pedigree; the coat is the receipt.

And the far end of the space

Deep in a pedigree, on an invented-colour coat, patterns appear that no genesis horse ever wore — brindle striping, marbling, belted bodies. A horse like this is not rare because we said so. It is rare because somebody spent generations getting there.
