What color is RAL Classic Black blue?

RAL Classic Black blue RAL 5004 is a near-black blue with a distinctly cool, inky cast. Its deep value makes it read almost black in dim rooms, while daylight reveals the restrained blue character beneath the darkness. Use this shade on cabinetry, interior doors, or a single wall where a strong outline is wanted without the flatness of pure black. Pale gray, chalky white, brushed steel, and light oak give Black blue a crisp, grounded contrast. On an exterior, it can give trim or a front door a sharp, shadowed presence against lighter masonry or painted siding.

LRV of Black blue

Black blue has an LRV of 4.62% 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 4.62%, 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.
