About Dunn-Edwards Old Mill
At LRV 4, Old Mill is about as dark as paint gets — it reads near-black on a wall and reveals its character only in direct daylight or under warm bulbs. 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. In rooms with little natural light it can feel heavy, so reserve it for spaces you want to feel enveloping.
Old Mill earns its keep as a statement: accent walls, a front door, cabinetry, a moody powder room, or exterior trim where you want sharp contrast. Blues calm a room, which makes them popular in bedrooms, bathrooms and home offices.
