You might want to go to houzz.com and search for kitchens with similar cabinetry. You might also want to post on the home decor forum....lots of helpful people there who love to suggest color schemes.... I would suggest that what you have now is very neutral and that you look for an inspiration piece....a piece of art, a plate, a fabric, whatever....that you like and around which you can build a scheme.

I just painted my walls in White Dove by BM. I have a subway tile backsplash in the kitchen with black grout. I'd like to paint my cabinets white and the island Navel (dark blue), but what color white should I paint my cabinets? The subway tile is a bright white and the WD if a very soft white/gray. Worried they will all clash or have too many shades of white going on. Help! :)

Stunning tile choices and lovely wood. (Agree I wouldn't want to clean those tiles, but luckily *I* won't have to, you will!) I agree to wait unit most of it is in place and then purchase large samples from Samplize and hold them up around the room. Jan nailed it - cozy, moody can be super chill. What you are putting together is a really high end look and you are not going to find good examples of it on Houzz. Look through inspiration pics onArchitectural Digest, 1st Dibs, and Galerie. Look at Farrow and Ball paint samples, even if you don't end up using that brand. They are good inspiration for nice saturated colors. I think a deep plum color would be beautiful in your space.

Food for thought: when people start getting cataracts, they tend to see things in a more yellow or even brown tint. I sometimes wonder if that’s why some people lean toward the cooler end of the spectrum. That being said, I don’t think 4000k is terrible for a bathroom or even a dark kitchen. It’s actually fairly neutral and still has a slight yellow tint. To my eyes, 3500k starts to look too yellow. Now 5000k is too much for most indoor places (though I use them in my basement). You are correct that CRI is important for color rendering, which may be important in a bathroom, especially if you are relying on it to put on natural looking makeup. But going too yellow or too blue will also affect the way we see color to some extent. After my mother had cataract surgery many years ago she came in my house and told me how much she liked my living room paint color. It was a pale yellow beige at that time. She said before her surgery the whole room looked like it was way too yellow and brown.
