Can you think of another animal with such color variations as horses?
I've often thought about that. Wild animals all tend to look alike. Domesticated animals have many breed variations, such as in cattle, dogs, cats, etc. Each breed has it's own color or markings that distinguish that breed from the others, but I don't think there is other animal that can challenge the horse for it's seemingly unlimited variations in color and markings.
Just think, if it weren't for marriage, men would go through life thinking they had no faults at all.
