We are searching for a backsplash to go with our Bianco Romano granite in the kitchen. Originally wanting to do 2 cm solid slab on the backsplash, but finding it impossible to match ita to our 3cm counter tops. Our kitchen is traditional, with cherry cabinets and and similar toned wood floors. Stainless appliances. We've considered white onyx subway, but not sure if it will compete with granite. Anybody have an idea or two?!
