From my observations and
assuming the texture is correct, the color of the skin indicates the color of the hair. Both in blue and tan areas.
Dark bluish skin = a wonderful dark steel blue hair color
dark flesh color/pink = deep golden hair color
In senior yorkies (7-8+yo) I have noticed that the blue skin becomes lighter.
The same applies to the pink skin.
Some yorkies also have running tan at the base of their tail, meaning that the tan is invading the blue area. The blue on the base of tail is surrounded by tan. You have tan on the underside of the tail and the breeches, and blue
only on the upper side of tail. (a small stripe).
That is why the standard asks for a darker color especially at the tip, where the blue and pink skin eventually join.
This is essential because it is like a guard, keeping the gold from running out of its territory.
A bit off-topic but there is a very interesting article written by Joan Gordon concerning the coat and color.
