Here's a picture of my most popular character on DA, Kathy the Cheetah.
Yellow: Her eyes, her fur
Black: Her hair, spots on her body, soles and laces of her sneakers, part of her tank top and shorts, her gloves
Red: Her sneakers, stripes on her socks, part of her tank top and shorts
White: Her cleavage and belly, her socks
Pink: Insides of her ears
Hope you like her.
