it can take up to two years for yorkies to get their full coloring. if you know your line then it shouldn't be hard to figure out what colors they will be. look at your pedigree. what are the coloring of the grandparents and so forth. it is best to have a pedigree w the same coloring so there is no quessing but that is hard to find when people just breed who ever to whom ever.
