yorkies skin color is supposed to be the color that the hair is going to be.
my boy (1 1/2 yrs)has a pinkish color and he is the lighter blue (silver) his head is light gold and so his his skin there.
my girl(6 yrs) is black and her skin his blue and her head is deep gold and her skin color there is gold.
seems like we all have the makings of some light colored babies here.
