Grey River Rock

Grey River Rock Technical Profile

What color is Behr Grey River Rock (HDC-SM16-02)? It's a medium cool gray — hex #99A1A1, LRV 35. The closest cross-brand equivalent to Grey River Rock is Vista Paint Raw Steel — a near-identical match on the wall, with Benjamin Moore Timber Wolf and Benjamin Moore Cobblestone Path also close. Its LRV of 35 gives Grey River Rock depth without going dark, which makes it a strong choice for accent walls, libraries, and rooms with abundant natural light. As a cool neutral, Grey River Rock 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, Grey River Rock 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 Grey River Rock holds its character across bulb temperatures, shifting only slightly warm under 2700K and slightly crisper under cool daylight.
