Farrow & Ball 5L Exterior Masonry French Gray No.18

French Gray, despite its name, leans heavily towards green. A beautifully subtle and indeterminate shade, it takes its inspiration from colours popular in French decoration in the 19th century, and creates very relaxed-feeling rooms. Its green undertone makes it a sympathetic colour for exterior woodwork, especially front doors.
