Bittergreen
What Bittergreen Actually Looks Like
Bittergreen lands somewhere between a mossy olive and a toasted brown. The hex reads as a medium-dark, muted earthy tone with clear warmth baked in. It is not a bright or saturated green in any conventional sense. On a large wall it reads grounded and quiet, closer to dried herb or aged bark than anything you would call leafy. The name gestures toward green, and you can see that green ancestry, but the brown pulls hard enough that many people will simply read it as a warm neutral from a distance.
Bittergreen Undertones
The RGB values place this color squarely in warm territory. Red and green channels sit close together while blue trails well behind, which produces a yellow-brown cast underneath the surface green. In low or cool north-facing light that warmth can tip the color toward a flat muddy brown. In warmer incandescent or south-facing light the olive character becomes more legible. Either way, expect the brown to do most of the talking.
Where Bittergreen Works Best
Because the LRV sits below 20, this is a genuinely dark color. It will absorb light and make a room feel more enclosed, which can be an asset in a study, library, or dining room where you want intimacy. It is not the right pick for a small bathroom you want to feel airy, or for a hallway that already gets little natural light. Large rooms with generous windows handle it well. It also works on a single accent wall where you want weight without committing to four dark surfaces.
Where to put Bittergreen
On all four walls in a living room with good south or west light, Bittergreen creates a cocooning effect that works well with leather seating, wood floors, and warm-toned art. Keep trim in a creamy off-white to stop the room from feeling too heavy.
Dining rooms are a natural fit for dark, warm colors like this one. Candlelight and warm pendant lighting will pull out the olive notes and give the room real atmosphere at dinner. During the day the color reads more brown, which still feels grounded and deliberate.
A study benefits from a color that signals focus and seriousness. Bittergreen delivers that without resorting to navy or charcoal. Pair it with wood shelving and a warm desk lamp and the space feels thoughtful rather than cold.
In a bedroom this color works if you want drama and enclosure rather than a light, restful retreat. Keep bedding in warm neutrals or deep terracotta. Avoid bright white linens, which will create too much contrast and make the walls look darker than they are.
What to Pair With Bittergreen
No coordinating colors are listed in our database for CSP-990 at this time. Generally, a color this warm and dark pairs well with off-whites that carry a cream or wheat tone rather than stark bright white, natural wood tones, aged brass hardware, and textiles in rust, camel, or deep teal.

Colors that clash with Bittergreen
Cool gray trim will fight the warm brown-green base of this color and make both shades look slightly off. The contrast reads muddy rather than crisp.
A stark bright white ceiling above a color this dark creates a jarring jump in value. In a room that already lacks light it will make the ceiling feel disconnected from the walls.
Polished chrome and brushed nickel fixtures read cold against a warm earthy brown-green. The contrast is not elegant, it is just mismatched.
Common questions
The LRV is 18.22, which puts it in the dark range. Colors below 25 absorb significantly more light than they reflect, so Bittergreen will make walls feel visually heavy. That is a feature in the right room and a problem in a space that already feels cramped or dim.
Our database lists CSP-990 as an interior color. Check with your Benjamin Moore retailer about whether the formula can be applied in an exterior base, as availability can vary by product line.
Eggshell is the most forgiving choice for walls. It gives just enough sheen to make the color feel alive without highlighting every surface imperfection the way satin or semi-gloss would. Flat or matte works in low-traffic rooms if you want the most depth, but it marks more easily.
Dark, warm-toned colors over white or light walls almost always need two full coats for even coverage. Ask your retailer to tint the primer toward the finish color to reduce the number of topcoats required and improve the final depth.
