Horse coat colors depend on the amount of natural colouring in its skin, or pigment.
A specialized vocabulary has evolved to describe them.
Color is one of the first things that is noticed about a horse.
Often, a horse is first described by its coat color rather than by breed or by sex.
While most horses remain the same color throughout life, a few, over the course of several years, will develop a different coat color from that with which they were born.
Most white markings are present at birth, and the underlying skin color of a horse does not change, absent disease.
Most horses and ponies have dark skin.
