A look at grey seal brown horses around the world and on a variety of different breeds.
The grey modifier can work on any coat color. An animal is born brown and slowly grow lighter as they age, until they become white. As with many of the other modifiers, it can be difficult to visually identify a greying brown animal. Their most identifiable factor is the light red colored hairs that grown around the soft spots, especially around the nose and greying can affect the lighter pigments as well.
