It's a version of bay. They've finally documented that brown is also caused by agouti, but a different form of it. So it's virtually the same as bay, just slightly genetically different. It still wouldn't show on a chestnut coat, like bay, but I believe can be carried by a chestnut and passed onto foals.
Agouti (bay horse) = A
Non-agouti (black horse) = a
Brown Agouti (brown horse) = At
I hope God tells her to smash her computer with a sledgehammer.
