Buckskin, seal brown, and loud appaloosas are my fave's.
Never owned one. I always fall for the needy horse, or go for broke, or potential sane trail master. So I've mostly had chestnut, bay, grey, a couple black's, a palomino, and a few paints.
Maybe some day I'll stick to my guns and find "the one" but my three are going to live forever so hopefully I'll never have to shop again. MUST... STAY... OFF... CRAIGSLIST!
