What color is Behr Thundercloud?
Behr Thundercloud S520-5 is a mid-tone blue-gray with a noticeably cool, muted cast. Its softened saturation keeps the blue from feeling overly bright, giving walls a calm, grounded look in bedrooms, home offices, or bathrooms. In north-facing or low light, Thundercloud can read grayer and slightly deeper, while warmer daylight brings out its dusty blue character. Pair it with crisp white trim, pale oak, weathered wood, or brushed nickel for a clean, restrained palette. It also has enough depth for cabinetry or an exterior front door when balanced with lighter surrounding finishes.

LRV of Thundercloud
Thundercloud has an LRV of 22.52% 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 22.52%, 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.
