What color is Farrow and Ball Ancona Blue?

Farrow and Ball Ancona Blue 9805 is a pale, muted blue-green with a soft greyed cast that keeps it from reading overly minty or icy. Its light value gives walls an airy look, while the gentle green undertone becomes more noticeable in bright daylight. In lower or cooler light, this shade can appear quieter and closer to a misted blue-grey. It suits bathrooms, bedrooms, and light-filled kitchens, especially on walls or painted cabinetry. Pair Ancona Blue with warm white trim, natural oak, pale stone, brushed nickel, or deep charcoal accents for contrast.

What are Farrow and Ball Ancona Blue undertones?

Ancona Blue appears as a mid-light, softly muted blue-green, with low saturation that keeps it gentle rather than bright. In the supplied digital sample, it reads mainly as a teal-leaning blue with a subtle green bias, though that shift is slight and can vary with surface, finish, and surrounding colors. Farrow & Ball describes it as its interpretation of duck-egg blue, which fits the visible balance of blue softened by a hint of green. Warm artificial light may bring out more of its muted greenish cast, while cool daylight can make the blue side appear clearer.
