Benjamin Moore

Cos Cob Stonewall

1483

Cos Cob Stonewall is a mid-tone gray with faint smoky green undertones that become more apparent under warm lighting. Its LRV of 26.16 places it on the darker side of the mid-range, giving it enough weight to anchor a room without closing it in. The green cast keeps it from reading as a flat, cool gray, adding a subtle earthiness to the overall tone.

It works well in living rooms, bedrooms, and offices where a composed atmosphere is needed. Pairing it with Benjamin Moore Simply White or Classic Gray creates a clean contrast, while Edgecomb Gray offers a softer transition. Hale Navy can serve as a deeper accent alongside it.

LRV measures how much light a color reflects, from 0 (black) to 100 (pure white). Below about 50 a color needs good lighting to avoid going flat, 60 and up helps brighten a room, and most whites sit above 80.
