The hair discoloration is from age. The skin discoloration can be from age or from an underlying allergy or yeast infection or low thyroid. If she does not itch, hair loss, or have a bad odor, then I would not worry about the discolorations on her skin. If you notice any of those signs, then your vet can do a skin sample and a blood test to check for a cause.
