My one regret with the black island is that I chose a shaker door without a bevel. Those little corners are hard to clean and the black shows everything! If I could do it over I would still do a black island but it would be a stained wood, painted black and then distressed. That way any nicks and bumps show wood and not a white chip. We are considering changing that down the road.

Your trim looks very white. I love B.M. Linen White with bright white. White, with pale yellow undertone, would look great with a purple front door. This idea, but darker…B.M. Black Raspberry

Custom paint can be mixed for any solid colour swatch the size of a quarter or larger. Sherwin Williams has SO many colours there should be one that is identical or nearly so to your wallpaper. Do not select the final colour in the store. My SW has such terrible lighting I take the pieces of paper outside in the sunshine before taking home to look at in the actual room.
