Blue Gray No. 91 by Farrow & Ball is a cool blue-grey made with a subtle blend of blue, green, and black pigments. It creates relaxed rooms that feel quietly established—like they’ve always been there. A cooler, more weathered version of French Gray, Blue Gray has an almost magical quality, gently shifting between blue and grey depending on the light and time of day.
Use it on walls for a calm, coastal feel, or on cabinetry and woodwork when you want a classic, softened statement colour that still reads neutral.
Recommended Primer & Undercoat: Mid Tones.
Complementary white: School House White.
