You can use subway glossy marble (which I think this is what you see here) wether it be carrara or regular marble, to create a herringbone pattern. The countertops look like a marble look countertop and thus the marble would look great. I noticed the glossiness of the backsplash and it does look a little brown, but they are def subways. Calcutta marble has more brown in it.
