Blue-Grey Slate reads as crisp and architectural — strong in modern spaces, with natural fixed elements (chrome, stone, glass), or as a quiet anchor. At LRV 13 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.

Blue-Grey Slate Technical Profile
What color is PPG Blue-Grey Slate (30BB 13/068)? It's a deep cool gray — hex #606672, LRV 13. The closest cross-brand equivalent to Blue-Grey Slate is Valspar Whale Watching — a near-identical match on the wall, with Farrow & Ball Wine Dark and Valspar Dark Night also close. With an LRV of 13, Blue-Grey Slate 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, Blue-Grey Slate 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, Blue-Grey Slate 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 Blue-Grey Slate in the room's actual evening lighting, not just at midday.
