What color is Benjamin Moore River Silt?
Benjamin Moore River Silt CSP-180 is a muted mid-tone gray-brown with a soft, earthy cast that keeps it from reading flat or cold. Its subtle warmth can bring a grounded look to living rooms, entryways, and studies, especially alongside natural oak, aged brass, and linen upholstery. In bright daylight, River Silt may show more of its dusty taupe and khaki influence, while lower light emphasizes its deeper gray-brown base. Use it on walls for a quiet, enveloping backdrop or on cabinetry when paired with warm white walls and stone countertops. It also complements charcoal, clay, creamy off-whites, and worn leather without creating a high-contrast scheme.

LRV of River Silt
River Silt has an LRV of 21.08% 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 21.08%, 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.
