I cross posted this in sport horse breeding - some good color genetics people over there.
California Chrome’s dam is Love the Chase by Not of Love. This foal is by the same sire as C-C, Lucky Pulpit. Lucky Pulpit is by Pulpit who is by AP Indy who is by Seattle Slew
Passionforfashion is by Old Fashion (grey/roan) who is by the Unbridled Song (grey/roan) by Unbridled out of the Caro (grey/roan) mare Trolley Song (grey/roan) Caro had a large% of greys
Ooopsie!
Not to worry about “Ooosies.”
The JC registers horses to KISS (keep it simple) to the betting pubic.
Grey/roan are ALL ‘genetically grey.’
Some horses like Devil His Due, Halo, and Sunday Silence are registered with the JC as “dark bay or brown,” when in fact, these horses are “genetically True Black.”
For some reason, the Halo/Sunday Silence line has had ‘out-cropping’ of ‘Dominant White.’
This foal has “other color aspects,” that I cannot address.
You might get a more complete answer in another forum. But different registries have different rules/codes/definitions.
As an aside TB racehorse Oxbow had NO grey parents: He is an anomaly. Either a “weird roan,” perhaps Chimerism or … ??
The more I’ve found the more I learn; the more they change the rules.

Does that foal need tattooing around the eyes?
I’ve read in genetics books that grey is a dominant gene. Don’t see as many greys as bays, but this foal looks like a pinto.
Grey is dominant; and at least one parent must be grey for the foal to be grey.
Oxbow is puzzling; registered a bay, he shows ‘roaning’. but don’t know if he is a true Roan.
Foal is a type of pinto: Rabicano, I believe.
oxbow is technically a roan. and his offspring are equally as gorgeous
Turf Club and Passionforfashion are both registered as ‘white’. The other I looked up said grey- Old Fashioned, and the others were chestnut and bay.
Do tb people ever double register because of color the way quarterhorses are done? Thoroughbred with the jockey club and Paint with a tb assc? I guess if they’re keeping the horse in a racing home it wouldn’t matter. But for a gelding with no speed it might get them into a better home after the track.
Gestalt; its very doubtful.
We had a “pinto” filly this year by Animal Kingdom.

He has roaning, but he’s not a true roan unless he carries that gene (Rn). Since neither parent was a roan, this would only be possible via mutation. I can’t seem to find any good photos of his tail from the back, to see whether he could be an extreme form of rabicano.
There is only one line of true roan Thoroughbreds, all descended from NZ stallion Catch a Bird, who himself was brindle (so, much in the way of mutation going on there.)
The foal appears to be dominant white - this coming genetically from the dam. Technically the foal is chestnut with a really large white marking covering most of the body.
No grey gene involved at all in either of these cases.
And yes, some horses are double registered JC Thoroughbred and APHA. Seems to be more common, understandably, among those breeding for color rather than those breeding to race.
