Another more point worth mentioning and then I'll drop the topic in fear of being called something worse than dork...
Remember that many overos actually express a mixture of two or even all three types of overo genes. The fact is that many Paints are a mixed jumble of overo. This can make it quite difficult sometimes to exactly identify a horse's pattern because it is, in fact, exhibiting characteristics of more than one type.
My other color experience is with appys as a kid, and I think they are even more of a gamble to predict what you are going to get.
I like Arabs - no preference for color, though Arab breeders spend a lot of time head-scratching about how to predict greys.
He's faking. He's getting all that stuff off the paint horse website.
I ain't fallin' for it.
