I am having some issues with the floor and the counter but now I would do a very simple large format subway tile ,what is that cabinet on the right by the entry? IMO you have enough black and I am not sure how the gold will connect to anything else in the space. To me hardware is like jewelry it needs to go with the outfit. I would keep the light very simple brushed steel and glass and the pulls in stainless then add a punch of color with a glass bowl or a vase of flowers on the counter top. That marble needs to be the star just like a fabulous black dress .

I see a doorway with an arch. Is this a Spanish style home? May we see the adjacent rooms? It’s really a black, white and brown kitchen. White subways would theoretically be fine, but matching whites is not trivial. What is the wall color?

Baskets and wooden trays on the counters would help tie in the floors.

@Patricia Colwell Consulting: cabinet on the right by the entry is simply wall cabinets, then there is a space for a double wall oven. At first, I thought that "champagne bronze" pulls would work because it would pick up the gold-ish swirls in the granite and the warm tones in the hardwood floor. But, yes, perhaps stainless steel would work best.

@eam44: not a Spanish-style home as far as I can see. The house was built in 1983 by Pulte and the arches were simply an architectural feature. The adjacent room is the living room area and it's a mess, therefore no pictures! ;) Wall color is white.

The Hood pendant would look great. comes in different finishes for the metal and the glass.

When you look at your kitchen, do you want your counters to be the jaw-dropper? If so, the bs is going to take a supporting, not a starring role. Given the modern look you’ve gone for, I would consider a back painted sheet glass bs, or else a monochromatic, charcoal, black, or white bs tile in gloss and matte finishes, like the Heath Ceramics tile shown below.

@Beth H. :Thanks for the great backsplash ideas! Yeah, I hear you about the white subway tile. It's boring, but "safe." ;)
