Slate Gray reads as crisp and architectural — strong in modern spaces, with natural fixed elements (chrome, stone, glass), or as a quiet anchor. At LRV 16 it reads as a deep, enveloping shade — best on accent walls, dining rooms, and spaces where atmosphere matters more than reflected light. Skip it if you want a cozy, warm room — cool neutrals can feel sterile under warm bulbs or in low light.

Slate Gray Technical Profile
What color is Dunn-Edwards Slate Gray (DEGR73)? It's a deep cool gray — hex #687177, LRV 16. The closest cross-brand equivalent to Slate Gray is Dutch Boy Plated Blue — a near-identical match on the wall, with Hirshfield's Backwater and Valspar Crucible also close. With an LRV of 16, Slate Gray creates a dramatic, enveloping mood — best on accent walls, dining rooms, and intimate spaces where atmosphere matters more than reflected light. As a cool neutral, Slate Gray pairs with cool whites for trim, gray-toned or rift-cut oak floors, and brushed nickel or polished chrome hardware. Black accents and natural greenery add contrast. As a deeper neutral, Slate Gray reads as a confident anchor — strongest on accent walls, cabinetry, and moody whole rooms that get enough natural light to keep it from going flat. Cool neutrals hold their crisp quality under 4000K+ daylight bulbs. Under 2700K warm light they soften considerably — particularly true for any blue or green undertone. Deeper neutrals can read close to black in low light, so preview Slate Gray in the room's actual evening lighting, not just at midday.
