When it comes to genetics my brain starts to shut down because it begins to look like math to me. But EquineColor.com tries to take make color genetics a little simpler to understand. Charts, photo galleries and other reference material help sort out the many colors and variations of horse coats. I may have to take my laptop out to the barn so I can decide what color my mare really is. I've been calling it bay, with a some white hairs throughout, and a white patch on her belly. But maybe, the combination has a name. Maybe I do have a horse of a different color.
