Sorry about the picture quality. I had to take the day God gave me, and then I had to fiend off half a dozen big horses.
I looked up silver dapple and silver black, and that looks right. He has the dapple markings, although in his yearling winter coat it is not likely they will photograph at all. His striking light mane and tail are not something I would expect on a blue at all. They almost look like they do not belong on him.
And yes, he looks like he is also roan.
I was thinking a smoky or sooty pale horse, but I am not a color person. I was plumb tickled when my last filly did not go grey in spite of the fact even the vet said she would.
If wishes were horses, good God what a mess.
