What color is Sherwin Williams Sea Mariner?
Sherwin Williams Sea Mariner SW 9640 is a deep, muted blue-gray with a distinctly cool cast. Its charcoal-like depth keeps the blue restrained rather than bright, giving walls a grounded, shadowy presence. In strong natural light, the blue-gray character is clearer; lower or warmer lighting can make it read closer to softened graphite. Use this shade for a study, dining room, exterior trim, or built-in cabinetry where a dark color can add definition without looking black. Pale oak, brushed nickel, matte black hardware, warm white paint, and light gray stone provide clean contrast alongside Sea Mariner.

LRV of Sea Mariner
Sea Mariner has an LRV of 6.68% 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 6.68%, 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.
