What color is Sherwin Williams Waterloo?
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.
LRV of Waterloo
Waterloo has an LRV of 12.97% and refers to Medium Dark which means that this color reflects very little light. Why LRV is important?
Light Reflectance Value measures the amount of visible and usable light that reflects from a painted surface.
Simply put, the higher the LRV of a paint color, the brighter the room you will get.
The scale goes from 0% (absolute black, absorbing all light) to 100% (pure white, reflecting all light).
Act like a pro: When choosing paint with an LRV of 12.97%, pay attention to your bulbs' brightness. Light brightness is measured in lumens. The lower the paint's LRV, the higher lumen level you need. Every square foot of room needs at least 40 lumens. That means for a 200 ft2 living room you'll need about 8000 lumens of light – e.g., eight 1000 lm bulbs.
