River Rock
What River Rock Actually Looks Like
River Rock is a very dark moss green that holds its green identity even at low light values. It does not read as black or brown in a well-lit room. You can see the yellow and brown warmth sitting inside the green, giving it an earthy, organic quality that feels grounded rather than cold. The green is real and visible, not a suggestion.
River Rock Undertones
The dominant pull is yellow-green with a secondary layer of warm brown. There is very little blue in this color, which keeps it out of cool-green or teal territory. The brown undertone becomes more prominent in low light or north-facing rooms, where River Rock can shift to feel closer to a dark olive or deep earth tone. In good natural light, the green pigment wins and reads clearly.
Where River Rock Works Best
River Rock is a good candidate for spaces where you want serious depth without going to a near-black neutral. Kitchen cabinetry in a well-lit room is a strong use case. It also works on a single accent wall, built-ins, or exterior trim where you want a color that registers as green but behaves with the weight of a dark neutral. In a dim room or one with north or east-facing exposure, plan for the brown tones to come forward and the overall effect to feel considerably darker.
Where to put River Rock
On lower cabinets in a kitchen with good window light, River Rock reads as a rich, earthy green with real depth. Pair upper cabinets or walls with a warm creamy white to keep the space from feeling closed in. The yellow undertone plays well against natural wood countertops or brass hardware.
In a room with limited windows, River Rock leans into its brown undertones and creates a cocooning, focused atmosphere. Use warm artificial lighting to keep it from going flat. Linen, leather, and warm wood tones all support it.
A single wall in River Rock anchors a neutral room without overwhelming it. In a south-facing space the green stays visible and active. In a north-facing room expect it to read darker and moodier, which can be a feature rather than a problem depending on what you want.
River Rock is available in exterior formulas and holds up visually against siding in beige, cream, or warm gray tones. It reads as a classic dark green from a distance and gains complexity up close.
What to Pair With River Rock
River Rock is a warm color at its core, so it pairs best with creamy whites, soft warm neutrals, and muted earth tones rather than bright or cool whites.

At this light value, River Rock absorbs a lot of light. In a small room with few windows it can make the space feel significantly smaller and heavier than expected.
Common questions
River Rock's Benjamin Moore code is 2139-10, the hex is #464233, and the LRV is 6.6, which puts it in the same very-dark range as well-known deep neutrals like Hale Navy and Wrought Iron.
In a room with good natural light it reads clearly as green, with the yellow and brown undertones adding warmth rather than muddying the color. In darker rooms or north or east-facing exposures, the brown undertones come forward more and the overall value drops, so it can read closer to a dark olive or earthy neutral. It does not read as black.
For cabinetry, a semi-gloss or satin finish gives you durability and makes cleaning easier. It also adds a bit of light reflection that helps a very dark color like this one stay visually present rather than flat. For walls, eggshell or matte keeps the depth without making every imperfection obvious.
