What color is Sherwin Williams Umber Rust?
Sherwin Williams Umber Rust SW 9100 is a deep, earthy brown with a noticeable rust-red cast. Its muted depth keeps the color grounded rather than bright, making it especially effective on a study wall, dining room, or front door. In strong daylight, the warm reddish undertone is easier to see, while lower light lets it read as a richer, more shadowed brown. Pair Umber Rust with creamy off-whites, warm beige textiles, aged brass, and natural wood for a layered look. It also has enough presence for cabinetry or a single accent wall when a room needs more visual weight.

LRV of Umber Rust
Umber Rust has an LRV of 10% 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 10%, 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.
