An albino in any breed (from Human to Canine) always has pink eyes. Albino means there is no color pigment.
Of cousre its possible to have a solid white Yorkie. If this pup has blue eyes than it is in not Albino.

White is a recessive gene as are blue eyes.
A more interesting side note is that there are several canine breeds evolving to new color schemes. I would be interested to know what in the enviroment is causing such changes accross the globe....
