Blue Grey Sky

32%LRV Value

Blue Grey Sky reads as crisp and architectural — strong in modern spaces, with natural fixed elements (chrome, stone, glass), or as a quiet anchor. At LRV 32 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.

Blue Grey Sky Technical Profile

What color is PPG Blue Grey Sky (30BB 32/067)? It's a medium cool gray — hex #9399A6, LRV 32. The closest cross-brand equivalent to Blue Grey Sky is Dutch Boy Purpled Gray — a near-identical match on the wall, with Hirshfield's Dusky Mood and Vista Paint Dusky Mood also close. Its LRV of 32 gives Blue Grey Sky depth without going dark, which makes it a strong choice for accent walls, libraries, and rooms with abundant natural light. As a cool neutral, Blue Grey Sky 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, Blue Grey Sky 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 Blue Grey Sky holds its character across bulb temperatures, shifting only slightly warm under 2700K and slightly crisper under cool daylight.
