About Behr Mystery
Mystery sits in the mid-range at LRV 30, so it shifts visibly through the day — lighter and more open in morning light, deeper and moodier after dark. Its blue undertone is the part to watch: it gets picked up by whatever sits next to it, so test it against your trim, floor and the room's main light before committing. South-facing rooms will pull it lighter and warmer, while north light cools it down.
Mystery is versatile enough for full rooms but has enough depth to anchor a space, so it suits living rooms, bedrooms and cabinetry alike. Blues calm a room, which makes them popular in bedrooms, bathrooms and home offices.
