She's really cute! :)
As for her color (I'm no expert), she just looks like your standard blue roan, maybe sabino with splash (I have no idea about paint characteristics but she looks like others that I've heard described as sabino with splash), paint.
Also, forgive me if this is rude to ask (feel free to ignore it if so), but I was wondering why you keep getting such young horses if you want a really broke one? I would have thought one that was 9-12 would probably be a better bet, while still relatively young... I don't know though, of course. :)
