Mouse’s Back No. 40 by Farrow & Ball is a quiet grey-brown classic named for the fawny coat of the British field mouse. With a subtle green base, it has a soft, understated character that suits rooms both large and small—calm, grounded, and never overpowering.
In underlit spaces, Mouse’s Back can read greener on walls, adding depth and a gentle, earthy shift. It also works beautifully as an accent on furniture, floors, or joinery when paired with traditional, heritage shades like Setting Plaster and Lime White for a relaxed, timeless scheme.
Recommended Primer & Undercoat: Mid Tones.
Complementary white: Slipper Satin.
