Deep Shale

20%LRV Value
Save

Deep Shale reads as crisp and architectural — strong in modern spaces, with natural fixed elements (chrome, stone, glass), or as a quiet anchor. At LRV 20 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.

Deep Shale Technical Profile

What color is Behr Deep Shale (PPF-38)? It's a deep cool gray — hex #737C84, LRV 20. The closest cross-brand equivalent to Deep Shale is Benjamin Moore Wolf Gray — a near-identical match on the wall, with Benjamin Moore Eclipse and Benjamin Moore Black Pepper also close. With an LRV of 20, Deep Shale 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, Deep Shale 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, Deep Shale 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 Deep Shale in the room's actual evening lighting, not just at midday.
