I would choose a solid gray or white over black. I think black with white cabinets has lost its popularity. You should be considering your backsplash now too, and you can do something there to make the kitchen more interesting.

I would think a solid or almost solid gray would look best.

I missed that this is for resale. Yes, let the new owner replace the counter with marble if they want it that badly.

Thanks all! It will definitely be a million-plus home. Much of the quartzite we are seeing is close to the same quote so we are willing to have a stand-out island since the kitchen is so important. For those that said a solid gray.. has anyone seen any materials/brands/colors they might recommend?

**And in addition to white vs black vs gray -- what materials might look best accompanying the marble? Silestone, Caesarstone, Granite? I'm overwhelmed with options.

Silestone and Caesarstone are essentially the same thing. You'd just have to see which company makes a color you like. Since you're using marble for the counter, I'd think that a quartz perimeter might be better because they have more uniform coloration. Granites usually have movement which would conflict with your marble. The exception would be absolute black, which would look great, but I wouldn't want it - can't find the grubby spots and it's sort of a light vacuum. OTOH, you're not going to live there and many people love the look of absolute black.

I will agree with others that have said let the new owners put in marble if that's what they want. In fact, I don't want to seem harsh but I will go one step farther and say that is even more true for a million dollar plus home. (If you can afford that price point, you will want the counter top of your choosing, and there are a lot of people that do not want marble). Case in point, our neighbours spent months renovating their $million plus house for resale. The first thing that the new owners did was rip it all out. I would probably stick with something neutral in quartz (just because I prefer it over granite) for both the perimeter and island.

I agree about the marble. Choose a subtle quartz for both the island and the perimeter. That marble is absolutely stunning but for someone who has a problem with a busy counter, they'll hate it. Best when selling to keep it simple and more generic. Hence the suggestion to choose a quartz

We used statuary marble on my island. My perimeter is white cabs and we used blue pearl. The blue pearl is actually a dark gray color with slightly blue flecks. There are bluer blue pearls (which I wish we had!), but we didn't know at the time and went with this charcoal color, which is easier to find. Here's a close up of our blue pearl perimeter.

Here are our island statuetto slabs.

Here is the whole thing after.
