Picture is too far away to tell for sure but one parent would have to roan in order for your filly to be roan. If she is grey, which is more likely, she might look like a roan to some at the beginning of her color change. The best way to tell is that roans will always have a dark head and lower legs, while a grey will have white hair mixed in on the head.
Another thing to note is that all these are colors and have nothing to do with the breed of horse.
