What color is Benjamin Moore Southern Belle?
Benjamin Moore Southern Belle 819 is a deep, muted blue with a clear cool cast and enough grayness to keep it from reading overly bright. Its medium-dark depth gives walls a grounded look, while the blue remains visible rather than collapsing into near-black. In daylight, this shade can show a softened indigo character; under warm evening lamps, it may appear deeper and more subdued. Use it in a study, dining room, or bedroom, or reserve it for cabinetry and a painted interior door. Southern Belle pairs particularly well with crisp white trim, pale gray-blue textiles, weathered oak, brushed nickel, and warm brass accents.

LRV of Southern Belle
Southern Belle has an LRV of 11.62% 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 11.62%, 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.
