I think she is just a light dun - probably will end up like her mom who's in some of the pictures.
One of my horses is actually this little one's great-grandfather! And he is the exact same colour as well
He was used as a stud by the people who "own" these horses for a few years and then I bought him, so it's pretty fun to visit the herd and see a lot of his grand and great-grand babies!
