About River Rock
River Rock (2139-10) is a very dark warm gray (greige) from Benjamin Moore with a warm yellow undertone. With an LRV of 5, River Rock absorbs most light. It creates a dramatic, enveloping look and suits accent walls, cabinetry and well-lit rooms.
In north-facing rooms the cool daylight tones down River Rock's warmth, so it can read a little grayer; south- and west-facing light brings the warmth forward. It's a good fit for accent walls, front doors, cabinetry and powder rooms. Next to Southern Vine (2138-10), it's darker.
How River Rock changes with the light
River Rock is a deep color. In north-facing or dim rooms it reads darker and cozier; in south-facing rooms it shows more of its color. Either can work, depending on the mood you want.
North-facing rooms
River Rock will read even deeper in north light: great for a cozy, enveloping room, less so if you want it bright.
East-facing rooms
River Rock will look warmer and brighter in the morning and cooler and grayer by afternoon; check a sample at both times.
South-facing rooms
South light keeps River Rock from feeling heavy, so deep colors work well here.
West-facing rooms
River Rock will glow warmer in the late afternoon.
