cdisimone - I have very similar color cabinets and granite in my kitchen except my backsplash is lighter and floors are very dark porcelain, wood look tile. I've been looking for a color that will work throughout the majority of my house too. After weeks of deliberating, I started with my dining room and painted Shoji White last night. Not sure I like it....it does not look warm or creamy in my house at all. It looks like a very light cool gray. :-( I was going more for a warm white so I can brighten things up but still have the warm, cozy feel. I'm going to give it a few days before continuing on through the rest of my house. My suggestion is to paint an entire wall or much larger sample on your wall before deciding!

Going to second the comment about the columns. The color is overwhelming and they, with the island, is dwarfing everything else. I suggest painting the the white of the rest of your trim, in the same semi-gloss. For the walls you need a color that works with both, the cabinets and the island. B.M. recommends Stone Harbor for Classic Gray. Stone Harbor will also go with the dark island.

I have Brazilian cherry floors throughout the first floor and also have walnut furniture. I have the following colors in various rooms: BM Bunny Gray, BM Moonshine, Behr Clear Moon. Greens, grays and creams are recommended for red-toned furniture/floors. I picked those colors 16 years ago before I knew that, LOL! I would really look at Moonshine, it is a very subtle grayed green color and is gorgeous.

You have posted before with pretty much the same dilemma. What did you decide for the trim? Your choices aren't working because of the natural light influence. You can't just pick a color from a sample and put it on the walls. And, no paintcolor is neutral because of the undertones. Classic gray has a fairly high LRV, making it an off white. However, the wrong natural light will make it appear pink/purple. That undertone will not work with the fireplace tile. The room doesn't look very bright and the dominant light is coming in the three windows and glass door. Consider this color instead of CG: I think it will work well with the fireplace. Try a sample by the fireplace and by the window trim. You may find you like the woodwork as is. If it is a go add a bit of this color into the scheme. I know monitors are very fickle with colors, but I think this rug is a winner with the tile and Natural Choice. Love the weave and how the background just hints at the vague blue tone in the tile. https://markandday.com/products/la-porte-traditional-cream-area-rug
