I agree crisp white and a change of handles would look great. Also a industrial grey would look amazing, especically with the exposed hardware. Obviously this all depends on the rest of your kitchen but you could be more extreme and apply something cheap like chipboard to the back and apply some fun wallpaper to make more of a feature of all the items that you will have on display.

I'm not doing walls until kitchen in. also waiting a while to replace our table with a slightly bigger one. I've always wanted a decent table. only 3 of us so maybe will use end of it for serving up. in the pics the island looks clear and usable. the reality is it gets covered with all sorts. Im thinking of a mobile unit as could put it against chimney breast some of time. It's a developing idea. I'm reluctant to finalise until we live with the kitchen for a while. so much to think about and I'm an over thinker!

Sorry no idea what those designs/colours are. Can you share some pictures?

Your kitchen plans sound absolutely stunning! For a warm neutral that complements your deep forest green cabinetry without leaning too pink or green, you might love Hardwick White or Charleston Gray from Farrow & Ball. Hardwick White has a beautifully soft, warm stone quality that works well in varying light, while Charleston Gray brings a refined taupe tone that pairs effortlessly with oak and antique brass accents. Both should add a timeless, elegant contrast while keeping the space warm and inviting. Hope that helps, and best of luck with your kitchen—it's going to look amazing!
