What color is Behr Restless Sea?
Behr Restless Sea PPU13-20 is a deep, muted blue-gray with a distinctly cool cast and a lightly weathered appearance. Its low saturation keeps the color grounded rather than bright, giving walls a calm, substantial presence. In daylight, Restless Sea reads as a softened slate blue, while lower or warmer lighting can draw out more of its charcoal-gray side. It suits studies, bedrooms, powder rooms, and exterior doors where a darker color can add definition without looking black. Pair it with crisp off-white trim, pale oak, brushed nickel, or warm leather for contrast, or use it on cabinetry against light stone counters.

LRV of Restless Sea
Restless Sea has an LRV of 7.37% and refers to Dark colors which means that this color almost does not reflect 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 7.37%, 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.
