Shetland Pony - Rabicano?

I've been told my Shetland Pony is rabicano... thoughts? He's a yearling.









So, what would his color technically be called? Sorrel/Chestnut with rabicano? I'm a real color dummy.

One more pic:

I think he might have rabicano. Does he can the coon tail going on? Hard to tell from the pics.
