Acorn
What Acorn Actually Looks Like
Acorn 1125 is a true medium brown, the color of a dried acorn cap or well-worn leather. It reads as a grounded, opaque brown in most conditions, neither too light to feel timid nor so dark it closes a room down entirely. In strong natural light it shows warmth and some reddish depth. In dim or artificial light it settles into a richer, darker earth tone that feels almost like a wood stain.
Acorn Undertones
The undertones here are warm, pulling toward orange and red rather than any cool or gray direction. That warmth means Acorn reads differently depending on what surrounds it. Place it next to cool whites or blue-gray trim and the orange cast becomes more noticeable. Pair it with creamy or warm whites and the color reads as a clean, straightforward brown. There is no green or olive shift to worry about.
Where Acorn Works Best
Acorn suits spaces where you want weight and warmth without going fully dark. A dining room, a study, a hallway, or an accent wall in a living room are all reasonable candidates. Because its LRV sits in the low twenties, it absorbs a fair amount of light, so it works better in rooms with ample natural light or layered artificial lighting. Small windowless spaces will feel noticeably dim with this color on all four walls.
Where to put Acorn
Acorn on all four walls creates an enveloping, warm atmosphere in a dining room. Use warm white on the ceiling and trim to keep the space from feeling heavy. Candlelight and warm-toned bulbs bring out the reddish depth in the color.
The color has enough visual weight to feel intentional and focused without being oppressive. Pair it with natural wood furniture and warm brass hardware and it reads as purposeful rather than muddy.
A hallway is a good place to commit to Acorn because the exposure time is short and the drama reads well in a transitional space. Keep the ceiling light and the floor grounded with a natural fiber rug or dark wood.
If full-room commitment feels like too much, use Acorn on a single fireplace wall or behind a built-in bookcase. It anchors the room without the light-absorption concern that comes with four walls at this depth.

Common questions
The LRV is 20.51, which puts it firmly in the medium-dark range. In practical terms, it will absorb more light than it reflects, so plan your lighting accordingly and test a large sample in the actual room before committing.
Eggshell is the most versatile choice for living spaces because it offers a little sheen to bounce light back without highlighting wall imperfections. Use matte or flat if the walls are older and have texture you want to minimize. Save satin for trim or high-traffic areas like hallways.
Benjamin Moore offers Acorn 1125 in both interior and exterior formulations. On an exterior, the warm brown reads well on shingle siding or clapboard, especially with crisp warm white trim. The color will deepen slightly on rough or textured surfaces.
A medium-depth brown like this usually needs two coats over a properly primed surface. If you are painting over a very light or very different color, ask your paint store about a tinted primer to cut down on the number of finish coats needed.
