Krimson Lake Blue reads as crisp and architectural — strong in modern spaces, with natural fixed elements (chrome, stone, glass), or as a quiet anchor. At LRV 8 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.

Krimson Lake Blue Technical Profile
What color is PPG Krimson Lake Blue (90BG 08/075)? It's a dark cool gray — hex #45515B, LRV 8. The closest cross-brand equivalent to Krimson Lake Blue is Kilz Kettle Black — a near-identical match on the wall, with Behr Evening Storm and Valspar Fly-by-Night Blue also close. With an LRV of 8, Krimson Lake Blue 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, Krimson Lake Blue 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, Krimson Lake Blue 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 Krimson Lake Blue in the room's actual evening lighting, not just at midday.
