To get a caramel pewter you would have to cross your het caramel with a het caramel pewter to get a 1/16 chance to get a caramel pewter in an egg (Visual Caramel * Pewter would not give you any visual caramel babies only hets). Caramel is just short for Caramel Albino unless I am missing something. My best recommendation is to do some reading online as to how recessive and Co-dominant genes work and how you can mix them together.
