Can't say I've ever seen a grey foot before. Interesting.

Windy is a light sorrel with flaxen mane and mixed tail. Her momma was a grey Racking Horse who broke into the sorrel/white Paint's pen. Windy does have a few white hairs at the very top of her tail and a small (quarter sized) white spot on her right side, a blaze with 'mapping'. Not a clue if she will change colors or not.

I'm horrible at genetics but thanks for the info!
