Im not sure if the brown is to light for a bay horse but oh well. You can change it. The gray-black color is for the mane, the yellow-white for the markings and appaloosa blanket, brown (whoch you can change) is the base color, blue for the eye (the one you can't see is brown she is hetrochemic), and the gray-brown-gold is for the muzzle/nose! (wow a lot of description!)
