Farrow & Ball does not publish LRV; this value is estimated from the color’s hex using standard relative-luminance calculation. The matte estate finish typically reads lower.
Duck Green is a seriously deep, saturated green that sits right at the intersection of forest floor and shadowed hedge. It reads dark in most lighting conditions, and in a dim hallway or north-facing room it can almost disappear into near-black. But give it some natural light, especially on a bright afternoon, and the green comes forward with surprising life.
This is not a trendy sage or a soft olive. It is a proper old-world green with the kind of weight you see in Georgian paneling and Victorian front doors. The depth is the headline here. It absorbs light rather than bouncing it, which makes surfaces feel closer and rooms feel more enclosed, in the best possible way.
In Farrow & Ball's Estate Emulsion, the chalky matte finish swallows even more light and gives the color a velvety, almost powdery quality. In their Modern Eggshell on woodwork, the sheen pulls out a touch more brightness and lets you see the green undertone more clearly.
The dominant undertone is green, full stop. This is not a green that leans heavily toward blue or gray the way some deep greens do. It stays firmly in true green territory, with a slight warmth that keeps it from feeling cold or clinical.
That said, context matters. Under warm incandescent bulbs, Duck Green can pick up a faintly earthy, almost olive quality. Under cooler daylight or LED light, the green reads cleaner and a touch cooler. In very low light it can lean so dark that the green becomes hard to identify at all, tipping toward a murky charcoal. This is a color you want to test on the actual wall, in the actual room, at multiple times of day.
Compared to greens that carry blue or teal undertones, Duck Green is straightforward. It is leafy and organic rather than aquatic, which makes it easier to pair with warm woods and natural textures.
Duck Green thrives in rooms where you want atmosphere. Think studies lined with bookshelves, dining rooms meant for evening use, or a front door that needs to announce something without shouting. Its depth makes small rooms feel deliberate and cozy rather than cramped, because you are leaning into the darkness instead of fighting it.
It is a natural for traditional period rooms, especially Georgian and Victorian interiors where deep greens were historically common. Full-height paneling, wainscoting, or an all-over wall application with white trim creates a classic contrast that never dates. It also works well on kitchen cabinets when you want a grounded alternative to navy.
One thing to keep in mind: because it absorbs so much light, it needs support. Good task lighting, warm metallic fixtures, and lighter surfaces nearby all help the color do its job without making the space feel like a cave.
A study is where Duck Green really earns its keep. Apply it to all four walls and the built-in shelving, pair with brass reading lamps and Skimmed Milk White (No. W7) on the ceiling, and the room becomes a quiet retreat that feels collected and serious without being gloomy.
Evening rooms love this color. Duck Green on the walls with Ash Grey (No. W9) on the trim sets up a rich backdrop for candlelight, warm wood furniture, and layered textiles. The color recedes just enough to let the table setting take center stage.
A front door in Duck Green reads traditional and confident. The color holds up well in exterior Full Gloss, where sunlight brings out the green undertone more clearly. It pairs well with stone, brick, and painted white or off-white surrounds.
On kitchen or bathroom cabinetry, Duck Green works as a sophisticated alternative to black or navy. Use it on lower cabinets with a lighter upper wall color and brass or aged-bronze hardware. The matte eggshell finish shows off the color's depth without looking too shiny.
In a living room, consider Duck Green on a single accent wall or below a dado rail. It anchors a seating area and gives warm-toned upholstery and natural wood furniture something rich to play against. Balance it with plenty of lighter textiles and good lighting.
Duck Green's depth means it needs companions that create breathing room. Skimmed Milk White (No. W7) is the natural ceiling and accent choice, offering a warm, creamy contrast that softens the intensity without looking stark. Ash Grey (No. W9) handles trim and millwork beautifully, splitting the difference between a clean white and a sympathetic neutral.
For color-on-color pairings, Oval Room Blue (No. 85) shares enough depth to sit comfortably alongside Duck Green without competing, and Yeabridge Green (No. 287) can bridge the gap as a lighter green in an adjacent room or on upper walls in a two-tone scheme.
A saturated yellow wall or accent next to Duck Green can create a jarring contrast that feels cartoonish, like a sports team palette rather than a considered interior.
Icy or chalky pastel blues sit uncomfortably next to Duck Green. The temperature mismatch makes both colors look confused, with the blue reading too sweet and the green reading muddy.
A pure, blue-white trim next to Duck Green creates a harsh edge that makes the green look heavier and dirtier than it actually is.
Duck Green has a true green undertone. It is not heavily blue, gray, or olive. Under warm lighting it can pick up a slight earthy warmth, and under cool daylight it reads as a clean, leafy green.
Skimmed Milk White (No. W7) for ceilings and accents, Ash Grey (No. W9) for trim, and Oval Room Blue (No. 85) or Yeabridge Green (No. 287) for color-on-color schemes. Brass and warm wood tones also complement it well.
It leans slightly warm for a deep green. It does not carry the blue or teal cast of cooler greens, which helps it pair naturally with warm metals, leather, and wood. In cool north-facing light it can read a bit more neutral, but it never tips truly cold.
Estate Emulsion gives the best result on walls, with a chalky, flat finish that enhances the depth and velvety quality. For woodwork and trim, Modern Eggshell adds a slight sheen that makes the green read a little brighter. Full Gloss works well on a front door.
Duck Green is Farrow & Ball No. W55. Its hex code is #415243 and its LRV is 7.6, which means it reflects very little light and reads as a genuinely deep, dark color on the wall.
It can, if the room has limited natural light and no lighter surfaces to offset it. The key is supporting it with a lighter ceiling color, reflective trim, good artificial lighting, and warm metallic or light-toned accessories. In rooms where moodiness is the goal, like a study or dining room, the darkness is an asset.
