I know of one particular horse born grey and white pinto out of two red and white pinto parents. I have always been curious about him and his color.
I'd bet my booties that one or both of this mare's parents carried silver, as red can do that.

The biggest problem with the minis especially, is the misleading "registered as" colours many of our horses have in their backgrounds. There are still many,
many people who call silver dapples,
grey horses... Sight-wise, they are correct, genetically...they are not.
Grey is Grey- there is no difference between a horse that takes most of it's life to go white and one that goes white almost immediately- unless there are other factors, such as Silver, at work.All Greys are Grey- ie a coloured horse going white.
They may turn from Bay to White in the womb- so you would have to check to see what base colour they are. They may take all their lives and still not be white when they die. There is no difference genetically.
Exactly, and
very well said.
There are several nicknames for grey horses, that also get folks confused. They generally refer to the "colours of grey" the horse will sometimes take on it's journey to white...should it ever get there.
Rose-grey--A reddish-pink-tinged grey, most light bays and chestnuts will take this tone.
Steel-grey--Many blacks and dark bays are called this, in the beginning of the greying process, when the white, and black hairs are about 50/50.
Dapple-grey--This one is most commonly mistaken with silver-dapples, easily so, as the names themselves are confusing. (I reallyprefer to use Rabbitfizz's term, silver-black) The horse has usually gotten quite white over the top half, but there are dark points, and beautiful big dark dapples down the sides and hips.
There are more, I'm sure, but these are the first that came to mind.
What about appys who do this as well?
That, is a whold different ball-game, and another
completely different set of genetics. Unless of course, one has bred appys with greys...and that, in my opinion, is a waste, as the colour will most likely to be lost. That is why in the "real" Appaloosa world, an appaloosa breeder would
never dream of breeding grey horses into their programs.
