Depends on what look you are going for.

For rustic, butcher block for the black cabinets and black or white for the island

First Modern, white with light grey veining on both.

Transitional, white or white with light grey veining on cabinets black on island

do you have any samples in the space yet? you have to bring some in and proceed with eliminations. a bit of work..... but what you think, isn't always the best pick, when you get down to it.

Call me crazy and soooo out of style, but I used Crema Bordeaux with black cabinetry and very light gray island. I like color and movement. Oops: Edited to say mine is granite; you were asking about quartz. Yep, out of style on that, too, but I've been using granite for 30 years, with quartz thrown in here and there in some kitchens, and I always go back to granite.

I would think matte black surfaces would be difficult to continually keep looking clean. I have no experience with this, so I could be wrong.

Mine are painted matte black and I was told to use a barely damp microfiber cloth to wipe them down - nothing with a chemical. So far, knock on wood, works like a charm. Also works very well on the painted gray island.

We just installed silestone eternal statuario in suede finish and they are amazing. I’m in love with my countertops. Now deciding what to do with cabinets ! Thinking to paint black!

I researched her and looked for a year. Very happy we went with Silestone

@Ally C would you update your experience with your Silestone Suede one yer later?
