OK, I have a question for all of you...in both the two photos the OP posted of the DAM, and the two photos Jill posted of her gelding--one clipped pic, and one natural winter coat pic---IF I had seen ONLY the clipped pic of either horse, I'd have ID'd it as a silver bay-BUT, if I had been shown ONLY the natural winter coat photo of each horse, I might well have said they were each 'only' a chesnut/sorrel, albeit w/ flaxen M/T---this because the 'telltale' slate grey on the lower legs of a silver bay simply isn't visible in the 'winter hair' photos...am I the only one who sees it this way?
I have three horses that are undoubtedly silver bay. My matriarch mare is a 'medium' red in natural coat, w/ lightening in her flanks)-Agouti?I'm not sure; I don't 'study' this color stuff as many do---but she DEFINITELY has a grey undercoat; she was registered by AMHA as a chestnut in 1982. My AMHR B mare was registered in 1993 as a palomino!--and she IS more 'golden' in tone, BUT, she is definitely a silver bay by definition-slate grey lower legs, definite silver in the base of the hairs of the mane-and, also, a grey undercoat. My old Pinto gelding's color spots are VERY DEEP red, and he has white clear 'up' all four legs, so no clues there, BUT, where his mane and tail are crossed by color, it is CLEARLY SILVER....and, he was registered by AMHA in 1986 as a chestnut pinto.
Three horses, three very DIFFERENT tones/shades of color--yet all silver bay. It is really no wonder that there is STILL a lot of confusion in correctly describing miniature horse color! The registries aren't too helpful, because their terminology often lags so far behind newer knowledge--but when horses have been first registered as foals, often unclipped, it is not hard to see why stated color is so often incorrect.....
I agree that the dam in the photos is a silver bay; honestly, not sure about the foal, but surely "looks like" 'just' a sorrel to me-but as I said, I don't study this stuff. One thing I do think--that there is ALWAYS the exception to the rule!
