What color is Behr Knighthood?
Behr Knighthood S550-7 is a deep charcoal gray with a restrained blue-violet cast. Its cool undertone becomes clearer in bright daylight, while lower lighting can make it read closer to a near-black slate. Use Knighthood on a study wall, dining room, or exterior trim where a dark, grounded color is wanted without the flatness of pure black. It also has enough depth for painted cabinetry, especially alongside pale stone counters, brushed nickel, matte black hardware, or light oak. Soft white, muted gray, and dusty blue accents keep the palette clean and connected.

LRV of Knighthood
Knighthood has an LRV of 9.23% 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 9.23%, 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.
