I had white subway tile with white grout and a couple of years later we had our cabinets refaced in white. I like white, but the backsplash just sort of blended into the background. I bought a product in a bottle from Homedepot that is similar to Home Shield, it was Grout Renew. They have 20 colors, I just chose gray so it would not be too different. I had to order the product and they got it about 5 days. I did it myself in about 2 hours, made a nice difference, the backsplash really popped afterwards.
