Cornish Rex Colors: All of Them (and the Black Rarity Myth, Counted)

Every registry accepts every Cornish Rex color (one odd exception aside). We counted CFA's own show record to test the "black is rare" claim, and it fell over.

The Cornish Rex color chart is the easiest on the whole site to summarise: everything. All five registries we read accept essentially every color and pattern on this breed, and Britain's goes furthest, scoring color at zero points in its own judging standard. What the internet gets wrong about this breed is not the palette, it is the rarity folklore: two of the biggest consumer color articles call the black Cornish Rex "rare" or "unusual," and 's own show record, when you actually count it, says the opposite. We counted. Here is the whole color story, sourced to the standards themselves.

Every color, five registries, one strange exception

RegistryThe color rule, in its own words
"CATEGORIES: All. DIVISIONS: All. COLORS: All"
Exhaustive named palette + "ORC: any other color or pattern"
"Colour and pattern are irrelevant and carry no points"
"Any coat colour, or combination of colours, or patterns is permitted"
"All colours allowed [except amber]"

's standard says it three times in one document: "CATEGORIES: All. DIVISIONS: All. COLORS: All," with white lockets and buttons explicitly permitted and, unusually, no eye-color disqualification of any kind, a rule even its own Devon Rex standard does not match. takes the opposite route to the same place: no blanket sentence, but an exhaustive named palette running three pages (solids, silvers, smokes, four tabby patterns across nine base colors, torties, calicos in dilute, chocolate and lavender, pointed colors, bi-colors and vans), closed with a catch-all class: "ORC (Other Rex Colors): any other color or pattern."

's judging standard is the bluntest: "Colour and pattern are irrelevant and carry no points." Canada's : "Any coat colour, or combination of colours, or patterns is permitted," with all eye colors accepted. And Australia's allows everything with a single exception nobody would guess: "All colours allowed [except amber]," the same lone exclusion its Devon Rex standard carries.

an ordinary named solid at all five

Two dedicated color articles, independently, call black rare on this breed: Catster ("The black Cornish Rex is a rare color") and Hepper ("it's pretty unusual to find a Cornish Rex with onyx hues"). Neither offers a sample, a count or a citation. So we went to the one dated record available: 's own breed page lists its titled Cornish Rex cats across eleven consecutive show seasons, 2015-16 through 2025-26. Counting every named color on that list, about 134 entries in all, color names containing "Black" (black, black-white, black smoke, black smoke-white, van black-white) account for roughly 60 of them: by a wide margin the most frequent color family on CFA's own page, ahead of chocolate, calico and every white variant.

One honest caveat, which is more than either article offered: a titled-cats gallery shows what breeders campaign, not a census of the whole population. But no registry anywhere flags black as restricted or unusual, and the only dated record in sight puts it first, not last. If you want a black Cornish Rex, the record says you are shopping in the breed's mainstream.

Calico and tortoiseshell Cornish Rex

The tricolours run on ordinary cat genetics, and the registries treat them as ordinary classes: defines the calico Cornish Rex as "a tri-color cat with un- medium to large patches of solid color and red, or dilute color and cream on a white background," and 's palette carries calico through dilute, smoke, chocolate and lavender versions. Like every calico and , they are almost all female (the two-X-chromosome story our calico guide tells in full), which is the honest reason a marketplace shows fewer of them than blacks or whites: not a Cornish Rex restriction, just sex-linked color arithmetic on a small breed.

White, pointed, and the small print worth knowing

The white Cornish Rex carries the fullest eye-color range in Canada's standard (blue, copper, gold, green, aqua, ) and one piece of British paperwork worth knowing about: requires a or OAE hearing certificate before any white Cornish Rex can be registered for breeding, the same white-cat hearing science our white cat guide covers with the actual rates. That is a registry rule about breeding paperwork, not a verdict on any individual cat.

Pointed Cornish Rex are a full color class at (seal through lavender points, points, points, blue eyes required), not a separate breed. The old name "Si-Rex," which you may meet in older books, was a 1980s-era American show designation for colourpointed Rexes that has lapsed: no current registry document we read uses the term at all. And Canada adds one genuinely obscure collector's item: the "caramelized" dilute modifier, a metallic sheen over blue, lilac, fawn or cream, with cream-based caramel wearing the fancy's best color name, "apricot."

What color was the first Cornish Rex? Depends who you ask

Every registry agrees on the founding story's frame: a farm cat named Serena, a tortoiseshell-and-white, gave birth to five kittens on Bodmin Moor, Cornwall, on July 21, 1950, and one of them, Kallibunker, wore the first rex coat. What they disagree on, to this day, is his color. and both say cream; says red and white. Nobody has corrected anybody, all three accounts are live on the registries' own pages, and since red and cream are adjacent shades in cat genetics (cream is red, diluted), the disagreement may be two honest readings of one seventy-five-year-old cat. We print both, attributed, rather than picking: it is the breed's own founding folklore, disagreement included.

Frequently asked questions

What colors do Cornish Rex cats come in?

Essentially all of them: every registry we read accepts every color and pattern, from solids and smokes through tabbies, torties, calicos, bi-colors and pointed. The single named exception anywhere is Australia's ACF excluding amber, a rarity most breeds never carry anyway.

Is a black Cornish Rex rare?

The claim circulates, but the one dated record available says no: counting CFA's own titled cats across eleven show seasons, black and its variants are the most frequent color family, roughly 60 of about 134 entries. No registry restricts or flags black on this breed.

Do Cornish Rex come in calico?

Yes: calico and its dilute, smoke, chocolate and lavender versions are ordinary named classes. Calicos are almost all female, as in every breed, which is why listings show fewer of them.

Can a Cornish Rex have points like a Siamese?

Yes: pointed is a full color class with blue eyes, at CFA and elsewhere. The old term "Si-Rex" for these cats was a lapsed 1980s American show designation, not a current breed or class.

What color was Kallibunker, the first Cornish Rex?

The registries disagree: CFA and GCCF say cream, TICA says red and white. All three accounts describe the same 1950 litter on the same Cornwall farm; we report both rather than picking a side.

Do white Cornish Rex have hearing problems?

White cats in general carry an elevated congenital deafness risk that rises with blue eyes, and GCCF requires a hearing certificate before a white Cornish Rex breeds in the UK. A BAER test answers the question for an individual cat; ask your vet or breeder.
