What color is Farrow and Ball Serge?

Farrow and Ball Serge 9919 is a deep, muted blue with a pronounced gray cast that keeps it from reading as a bright navy. Its cool, low-saturation character gives walls a grounded, shadowy look, especially in rooms with limited daylight. In brighter light, the blue becomes clearer while the gray undertone still softens the overall effect. Serge is particularly effective on cabinetry, a study wall, or a small dining room where a darker color can create definition. Pair it with chalky off-whites, pale gray stone, brushed nickel, or natural oak for contrast and warmth.

What are Farrow and Ball Serge undertones?

Serge is a deep, muted blue with a low-key, slightly gray cast rather than a bright or vivid navy. The supplied digital sample reads close to neutral between red and green, while its blue direction gives it a cool overall character; any undertone is best understood as that relative blue bias, not as a fixed hidden pigment. Farrow & Ball describes Serge as a shade named after the original denim fabric, but the official text provided does not specify an undertone. Warm artificial light may soften and slightly dull its blue appearance, while cool daylight can make its blue character look clearer.
