What color is Sherwin Williams Loyal Blue?
Sherwin Williams Loyal Blue SW 6510 is a deep, cool blue with a noticeable teal cast, giving it more complexity than a straightforward navy. Its rich saturation holds up well on an accent wall, built-in shelving, or kitchen cabinetry, where the dark color can create clear definition. In bright daylight, Loyal Blue shows more of its blue-green character; in lower light, it settles into a darker, inkier tone. Pair it with crisp white trim, pale gray stone, warm oak, or brushed brass for contrast against its cool depth. It can also bring a grounded, dramatic finish to a front door or covered exterior detail.

LRV of Loyal Blue
Loyal Blue has an LRV of 4.98% 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 4.98%, 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.
