What color is RAL Classic Steel blue?

RAL Classic Steel blue RAL 5011 is a deep, cool blue with a restrained charcoal cast, shown here as #1A2B3C. Its low brightness gives it a near-navy appearance, while the muted blue character keeps it from reading as flat black. In bright daylight, Steel blue can appear clearer and slightly more blue; under warm evening lighting, it settles into a darker, ink-like tone. It suits exterior doors, built-in cabinetry, paneled walls, and small architectural details where a strong dark color is wanted without a glossy or overly vivid effect. Pair it with soft off-whites, pale gray stone, brushed steel, natural oak, or warm leather for contrast.

LRV of Steel blue

Steel blue has an LRV of 5.44% and refers to Dark colors which means that this color almost does not reflect light. Why LRV is important?

Light Reflectance Value scale illustration

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 5.44%, 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.
