IMO your home should be a reflection of you and what you love. I always have a main bathroom in blue. Through the years, I have changed the color of my walls many times in the other rooms. Currently my kitchen is a neutral green, gray, plum color. It changes color depending on the light. My DR is green. My LR is a cream with hint,of green tint. My master BR is burgundy. I am thinking about repainting my master. I haven't decided on a color yet. I have 2 nephews who just built houses. Their main living areas are colorful. Teal and purple seem to be popular.
