I think when the cabinets are white, just the similarity to the white dining room uphostery will make the spaces more cohesive. I got lost in reading all the posts, so can’t figure out what you’re doing colorwise with the 12” deep cabinet, but hopefully it will match the white cabinets. I wou would try to think of how to bring something dark into the kitchen, like maybe black or dark orb hardware. Apologies if I missed that. Perhaps the legs of your island could be finished in espresso? I’d love that big island for prep!
