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.
