Why not butcher block on a painted island and a different counter material on the perimeter cabs? Meanwhile here are some hickory kitchens to put into your idea file. Hickory with a wood island... The images below are not all hickory, just wood with wood Not Hickory but you can see that wood with a wood top can be too much. I like that this island is painted red. \

Gray taupe would be pretty and maybe a green with a gray undertone? I have also taken pics of my house with samples of my cabs and counter to sherwin Williams or Ben Moore and have found their paint experts to be spot on picking the right colors. Sometimes computer monitors can show colors way different than they appear in real life. I really like your cabs by the way!

I agree - love the floor but I think I would go with something simpler. I would look at different countertops, too. I know people (like someone above) always say that keeping things a darker single color makes a small space look bigger, but that's never my experience! I always think an all white space looks the biggest! So I'd do the white shaker cabs with maybe a white countertop and backsplash. We've purchased the pure white quartz from ikea, as well as the pure white acrylic (corian) and both look great and modern. If you think this house might appeal to some artsy hipster types, I also like the Marsta door which channels a midcentury vibe. It is on supersale right now. The space is small so I'd bring in interest with hardware and a lighting fixture.

You have been shown some nice examples of dark and light. Mine is a light quartz - there is cream, gray, white and a little beige in it. There are a number of quartz that read warm but light. I went with a simple cream backsplash. You do not need one, but if you do a backsplash, keep it very simple. Your wood cabinets have movement and a backsplash that also has a lot of movement could look busy. My sink is the Kohler Whitehaven in the "short apron" style, should that style appeal to you. It can easily be installed on a standard sink base cabinet. https://www.houzz.com/photos/my-pics-work-in-progress-phvw-vp~93784356 countertop: https://www.houzz.com/photos/my-pics-work-in-progress-phvw-vp~54988831
