I am a fabricator. Don't pick based on computer images. For technical reasons a computer display cannot replicate a color hue exactly. (your eye can discern differences in hue that a computer or phone display can't.) Get samples of the candidate materials and then look at them in the new location, preferably mid and late day. This approach is imperative if you are fussy about color.

Just installed the Laza in my kitchen. I could not be happier. The veining is long and beautiful, dark gray with a slight taupe tint.
