We are remodeling an old farmhouse kitchen. The walls will be a light yellow and the "simply made" cabinets are antique white. We will have white appliances. I have picked blue pearl granite ( very dark navy ) that has silvery flecks scattered throughout. Dilemma: not sure if we should use a backsplash, and if so, what material and color( tiles or granite ) should be used. We also have a small kitchen island. I plan to put honed whitish marble on this. Thank you for any advise you can give.
