What color is Sherwin Williams Lupine?
Sherwin Williams Lupine SW 6810 is a medium blue with a softened, slightly gray cast that keeps it from reading overly bright. Its cool blue character is clear, while the muted saturation gives the color a grounded, painted-plaster look on broad walls. In daylight, Lupine can appear cleaner and more open; under warm lamps, it tends to deepen toward a duskier blue. It suits bedrooms, studies, and powder rooms, and also makes a considered choice for built-in shelving or a painted front door. Pair it with soft white trim, pale oak, brushed nickel, charcoal accents, or warm tan leather for contrast.

LRV of Lupine
Lupine has an LRV of 16.39% 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 16.39%, 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.
