Years ago we had a horse. I think he was supposed to be a bay roan, but minus the black, no matter how you looked at him his coat looked PURPLE... I have never seen another horse like him. I'll see if I can google up a horse close to his colour here
Here's a picture of me next to her, you can get a sense of her size. She's a good sized girl for a mustang. I'm 5'6''. Anything much taller than she is, and I have issues getting up in the saddle without a crane.
