Shes only two months so it may not show yet. I do think it will show if you clip her. I had a couple foals look just like this though that I thought were bay and when clipped were black. She has some small white socks so that will make it harder to see black points on the legs
What colour are her sire and dam. That should give you a bit of a hint. So far, she looks black. If her eyes remain blue, then she carries Splash. She also could carry frame, even though she is solid. You'll need to test her for that before ever breeding, if it's something you plan in the future.
The sire was all black, the roan is the dam. I'm not clipping her, I can wait for her true color to show, its just all new to me. I don't know if this will help any, but the sire of the roan is palomino and the dam is a blue roan.
