My horse was always afraid of the color green. He hated it so very much! You know those turtle sandbox's? There was one we would have to pass on the way to the pasture and he would always get very jumpy around it. But it wasn't just the sandbox, anything that was that color green would make him freak out. I have always been told that horses are color blind but I find that hard to believe because of his reaction. What would cause this?
