Should white gold turn yellow

These days most white gold is rhodium plated, so what you see when the jewelry is new is the rhodium plating. As the plating starts wearing off, you begin to see the underlying metal. The underlying white gold should be quite white so that a little wearing thin of the plating is not very noticeable; but many times the underlying white gold is not white enough these days and the contrast is too obvious. Some center-aisle-of-the-mall kiOSks even rhodium plate regular yellow gold. In this case the discoloration shows much too soon.
