I am looking to install Caesarstone Calacatta Nuvo in my kitchen on island and surrounding countertops. Cabinets will be Benjamin Moore Chelsea Gray. I can't decide on a backsplash- I love Carrera Marble Herringbone but worry that will compete (or not match and be too casual) with the countertops. Do you think that matches or would you go with white subway tile or glass tile to keep simple? Any other suggestions? Thank you!
