I've always admired cal kings and easterns with especially white rings/chains. Some seem a little murky and it seems that's a result of their having black skin beneath the white scales--on a well fed snake the black shows through at the edges.
I haven't done a careful study of this, and don't have anything at hand to examine for confirmation. Do some kings, in fact, have white skin behind the white scales (and black skin behind the black scales?)
