What color horse will you get if you breed a chestnut paint with a sorrel paint?

Sorrel and Chestnut are genetically the exact same color. It is nothing more than a difference of terminology.

1. In most English riding circles Sorrel refers to a chestnut horse with a flaxen (blonde) mane and tail. While chestnut is a solidly chestnut body, mane and tail.

2. Some western stock breed registries use sorrel to mean a darker shade of chestnut with matching mane and tail. And chestnut for lighter shades, with or without a flaxen mane and tail.
