You didn't say how old she was when you got her, was she still a pup? Yorkies coats change color, they start out as black and tan. As they get older the black is suppose to change to a steel blue and her tan should be a golden tan that lightens towards the end of the hairs. The color change takes awhile and may not be complete even after 1 year of age. So, I would say it is all normal and to be expected.
