What color is Benjamin Moore River Rock?
Benjamin Moore River Rock 2139-10 is a deep, muted charcoal-brown with an unmistakable olive cast. Its low-light value gives walls, cabinetry, or a front door a grounded, substantial presence without reading as black. In brighter natural light, the earthy green-brown undertone becomes easier to notice; at night, it can settle into a nearly blackened taupe. Pair River Rock with warm off-whites, aged brass, natural oak, and textured linen to bring out its organic side. It is especially effective on built-ins, kitchen islands, and small accent walls where its depth can be appreciated up close.

LRV of River Rock
River Rock has an LRV of 6.6% and refers to Dark colors which means that this color almost does not reflect light. Why LRV is important?
Light Reflectance Value measures the amount of visible and usable light that reflects from a painted surface.
Simply put, the higher the LRV of a paint color, the brighter the room you will get.
The scale goes from 0% (absolute black, absorbing all light) to 100% (pure white, reflecting all light).
Act like a pro: When choosing paint with an LRV of 6.6%, pay attention to your bulbs' brightness. Light brightness is measured in lumens. The lower the paint's LRV, the higher lumen level you need. Every square foot of room needs at least 40 lumens. That means for a 200 ft2 living room you'll need about 8000 lumens of light – e.g., eight 1000 lm bulbs.
