About Dunn-Edwards Black Jack
At LRV 8, Black Jack 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. Because it carries almost no measurable hue, it stays a true neutral and pairs cleanly with nearly any trim or floor. In rooms with little natural light it can feel heavy, so reserve it for spaces you want to feel enveloping.
Black Jack earns its keep as a statement: accent walls, a front door, cabinetry, a moody powder room, or exterior trim where you want sharp contrast. Grays like this read as a modern neutral and sit comfortably alongside both warm woods and cool metals.
