Sherwin Williams Waterloo SW 9141 is a muted blue-gray with a noticeable slate cast and medium depth. Its subdued saturation keeps it from reading overly nautical or bright, giving walls a grounded, slightly smoky appearance. In cooler daylight, Waterloo can lean more blue, while warm lamps tend to bring forward its gray-green undertone. It suits studies, bedrooms, powder rooms, and built-in cabinetry, especially alongside warm white trim, pale oak, aged brass, and charcoal accents. For a stronger contrast, pair this color with creamy plaster tones or soft terracotta textiles rather than crisp, icy whites.
