Powder Mill reads as crisp and architectural — strong in modern spaces, with natural fixed elements (chrome, stone, glass), or as a quiet anchor. At LRV 43 it carries real depth without going dark — a good choice for accent walls, libraries, and rooms with abundant natural light. Skip it if you want a cozy, warm room — cool neutrals can feel sterile under warm bulbs or in low light.

Powder Mill Technical Profile
What color is Dunn-Edwards Powder Mill (DET566)? It's a medium cool gray — hex #9CB3B5, LRV 43. The closest cross-brand equivalent to Powder Mill is Benjamin Moore Colorado Gray — a near-identical match on the wall, with Behr Harmonious and Colorhouse Water .04 also close. Its LRV of 43 gives Powder Mill depth without going dark, which makes it a strong choice for accent walls, libraries, and rooms with abundant natural light. As a cool neutral, Powder Mill 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. At mid depth, Powder Mill grounds a space without darkening it — it holds up on lower walls, kitchen islands, and as a wraparound where a lighter neutral would feel washed out. 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. At mid depth Powder Mill holds its character across bulb temperatures, shifting only slightly warm under 2700K and slightly crisper under cool daylight.
