Sherwin Williams Limestone SW 9599 is a muted, medium-dark gray with a noticeable earthy brown cast. Its low saturation keeps it grounded and quiet rather than overtly warm, while the slightly softened green-gray quality may appear more apparent in indirect daylight. In brighter rooms, Limestone can read as a worn stone gray; under warm bulbs, it settles into a deeper taupe-brown. It suits studies, dining rooms, exterior trim, or cabinetry where a darker neutral is wanted without the sharpness of charcoal. Pair it with creamy off-whites, natural oak, aged brass, blackened metal, and textured linen for a layered, material-focused look.
