If snowy has any coloring at all (freckles on her skin, ears, nose) I do not think it is something you should worry about. Do you have a picture of her? My Mandy is all white but as she got older she got loads of freckles on her skin. She also has a patch of fawn, about the size of a pea, on her cheek under her ear. Noone would ever see it unless I showed it to them.
