Are you replacing the cabinets or painting them? Have they been painted before? What is your plan for the backsplash?

I would recommend white. I think white always gives off a cleaner look, but that's just my preference. You have a beautiful space to work with. Get creative & have fun with it. I've attached some design inspiration below.

I like the look of white cabinets, upper and lower. I would also keep the island white, since it's the same style as the perimeter cabinets. A classic white subway tile backsplash would complete the look.

We are replacing the cabinets- they are falling apart -not apparent from Photos. I like the idea of all white perimeter and gray island- thoughts on that? Dark or Light gray?

White cabinets, black island, gray/white marble look quartz countertops. This color combination will always be in style.

Do white cabinets, you should not change the colors of the stone, between the island and the rest if the kitchen. designers these days, always trying to be unique. You will be happy with the same color. You are going to sell the home at some point, make it friendly to you and the next buyer.

if you must do gray, do a darker gray for the island

however, blue is the new gray. Or compromise and do a Blue-gray.

these shades of blue in these pics all look fab w/your oak flooring.

oh,,countertops,,, SuperWhite Dolomite

and Cielo Quartzite,,,this one is leathered

If you want a grey island, have a grey island and enjoy it! I have white cabinets with marble-look quartz and I really like the combination. It's your kitchen, so pick colors and materials that make you happy.

I assume this is an open concept kitchen which is open to your Great Room/LR/Family room. What are the colors there? Pictures? This should really dictate what you do in the kitchen.

Thank you all!!!! You helped me see and think from different perspectives...I keep going back to white perimeter and darker grey island- and I like idea of keeping all counter tops the same and I really like statuario quartz- the gray white marble look. I LOVE the idea of the blue or blue/grey cabinets too... I feel like a contrast will be good
You are all amazing and thank you for helping me!!!

I would keep the cabinets as is and focus on updating the counter top and the back splash which are dating your kitchen. No gray cabinets. Gray is a "dirty" color, kitchens need to look clean, and it's too trendy, it will date your kitchen very quickly when that trend passes. Remove that pot rack, it is making your kitchen look not clean and messy. Remove those chairs, that island is not big enough to have stools around it. Declutter your counter tops, you have too many functional appliances and nothing attractive to look at. Upgrade your cabinet hardware to knobs and pulls that are bigger, those are too small and boring, they're not adding any impact.
