Folks, how many black horses are there with white stars?

LOTS. So you cannot claim it to be yours when it is a generic horse colour. You can't see the feet either so it could have leg markings. But there is always a chance any realistic design you come up with for a non-paint or a non-appaloosa horse is a real somewhere in world.

Claiming a black horse with a white star is like claiming a bog standard bay horse with no markings. It's a basic and common marking, not very unique at all.
