Calico pony is a term used to describe a horse with a spotted, or mottled, coat with three distinct colors - black, white, and orange. While 'calico' may be the most commonly used term, there are other synonyms used to describe this unique color pattern. Some of these synonyms include piebald, pinto, skewbald, tri-color, and variegated. Each of these terms has a slightly different meaning and may refer to varying degrees of coloring or patterning on the horse's coat. Regardless of the term used, a calico pony is a striking and distinctive looking animal that is sure to turn heads.
