Where did the gray horse originate?

The first true gray horses may have originated in Spain, where they were developed from Andalusian and Barb horses. The gray coat color was further refined in France, where it was used to produce the elegant gray Percheron and Norman draft horses. Gray horses were also popular in England, where they were used to create the Cleveland Bay and Yorkshire Coach Horse breeds. Today, gray horses can be found all over the world and are used for a variety of purposes, including racing, show jumping, and dressage.
