He's a roan your right. They change colors all the time so at times he's got a line. Heck sometimes he just looks sorrel. I've got a blue mare that goes from white body to black then grey. Kinda strange.

My grey 2 yr old still looks black or sorta salt and pepper looking. He will get grey as he ages and will be solid white when he gets older. We normally just keep them for a few years and sell them. I/we enjoy working,breaking,training the young horses. I'm sure ill outgrow that one day...lol.
