I love the bays, buckskins, grullas and bay duns, all of them always look clean...lol.
My husband likes all black horses, but they look dusty all the time and it drives me nuts.
I am anal about keeping white clean also, but I do like the way it looks, but yes it has to be minimal, I like around 25%. And I love when they have all white feet. And since I have a mare with a bald face, I dont want to get another one, it is a pain to keep her from burning.
But health and confirmation are way more important! And I want a good solid working horse, as I also do Mounted Search and Rescue, and I want something that can take a hard ride, and also be sane. (My morgan cross LOVES it, she was born for it)
