You are lucky, you have a very neutral palette so you could go with many different colors. Quartz would be nice and practical. If you are planning to sell your home, you should keep things quiet and stay in the warm palette that coordinates with your wood tones. If you are never moving, go find your dream counter top as well as a beautiful back splash that would go from counter top to upper cabinet bottoms! A very dark top would blend with the stove top and visually would seem like you have more length. (Not cut up by light surface and dark surface). Consider an under counter stainless sink while you are at it and a beautiful new faucet. . .

Have fun!

I agree Quartz would look really nice in your kitchen. Neutral colors such as Swan (picture below) and Biege (picture below) would looks great, maybe add some neutral backsplash (Picture below - Corry 45). Change it up by adding a Siligranit (Picture below - Siligranit).

Good luck with your kitchen! www.sognaretile.com
