What color is Benjamin Moore Autumn Brown?
Benjamin Moore Autumn Brown 2099-40 is a muted medium brown with a soft, rosy warmth visible beneath its earthy base. Its #A17D71 color value gives it a gently weathered appearance rather than a dark, heavy brown, making it well suited to living rooms, dining areas, or bedrooms that need more depth than beige. In bright daylight, the color can read lighter and dustier, while lower or warmer lighting brings out its warmer brown cast. Pair Autumn Brown with creamy off-whites, faded clay tones, natural oak, linen upholstery, and aged brass for a layered, grounded interior. It has enough presence for full walls but can also give cabinetry or a painted accent wall a subdued, tailored look.

LRV of Autumn Brown
Autumn Brown has an LRV of 24.23% 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 24.23%, 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.
