Sherwin Williams Castlegate SW 9558 is a muted, medium-light gray with a faint cool blue-green cast. Its low saturation keeps it from reading icy, while the slightly deeper value gives walls more presence than a pale silver gray. In bright daylight, Castlegate can look clean and gently mineral; under warm lamps, it may settle into a softer, more neutral gray. It suits living rooms, bedrooms, and home offices where a calm gray is wanted without a stark white backdrop. Pair it with crisp off-whites, charcoal accents, weathered oak, brushed nickel, or black metal for a grounded, contemporary finish.
