Bay. Black points. Small star. No other white. Basically, my Gemmiecakes.
Dusty says it is boring, but I love a shiny bay butt with some back points. White annoys me solely because it is impossible to keep clean here in the red clay world of the southeast and I am nothing if not a keep it simple, low key horse owner. My horse lives outside, gets to keep all her hair and maybe gets a blanket thrown on a few times a year. I make sure to groom her before every ride, but the dark coat goes a long way to help hide a lot of dirt.
Having said that, color is my least important factor in purchasing a horse, so who knows. I may find myself owning a palomino (my least favorite color) some day. Stranger things have happened.
