Yes, his coloring is fantastic. It's like a regular gray, but then it has misty shadowing of darker colors underneath. It reminds me of a amazing horse I met out west that was a very pale buckskin paint with a light gray mane and tail and nearly colorless blue eyes. Amazing, especially when we were chasing him through the trees at dawn. But that's a story for another time.
Anyways, I second the Paint/TB. He's very tall and leggy and just kinda "sporty", too much so to make me think full paint, or QH, ect. But he has the paint coloring, and he has bigger bones than most TB. But he's only 3. He'll grow some.
He's a stunner though! I can't wait to see him when he's grown up a little and put on some muscle!
