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.
I've learned form experience that color should be the at the bottom of deciding if you want a certain horse or not. You need to look past color at conformation and attitude. I'm not real fond of greys either, but I've also learned, it's more how one is built if they are really pretty or not. I'm not that fond of Harleys color, but I think he's a beautiful horse. He's just put together so well that makes him pretty. Rusty's confirmation is pretty good to, not as good as Harleys tho. Color is not what makes them pretty, it can just make them prettier:)

FWIW...there's a Yahoo group that 'specializes' in apps. (the Appaloosa Project) I'm on the mailing list, but it's so darned 'technical' I'm 'lost'. LOL. Signed up for it to try and figure out 'what kind' of app Rei is.
