What color is Sherwin Williams Cornwall Slate?
Sherwin Williams Cornwall Slate SW 9131 is a muted mid-tone gray with a noticeable softened olive-beige cast, reflected in its gently earthy #949488 color value. It reads warmer than a blue or charcoal gray, though it still has enough restraint to feel grounded rather than tan. In bright daylight, Cornwall Slate can appear like a weathered gray-green neutral; lower or warmer light tends to bring out its khaki undertone. Use it on living room walls, built-ins, or exterior siding with creamy off-whites, deep brown wood, aged brass, and natural stone. It also pairs well with darker olive greens and near-black accents for a layered, organic palette.
LRV of Cornwall Slate
Cornwall Slate has an LRV of 29.13% and refers to Medium colors that reflect a lot of 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 29.13%, 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.
