What color is RAL Classic Cobalt blue?
RAL Classic Cobalt blue RAL 5013 is a deep, dark blue with a restrained, slightly muted appearance. Its low brightness gives it visual weight, so it reads as more grounded than a bright primary blue. Use this shade on cabinetry, a study wall, or exterior doors when you want a strong blue that does not dominate with excessive intensity. In bright daylight, Cobalt blue can show its clearer blue character, while lower light makes it appear closer to navy. Pair it with crisp white, pale gray, natural oak, brushed steel, or warm tan leather for contrast and texture.

LRV of Cobalt blue
Cobalt blue has an LRV of 6.1% 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 6.1%, 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.
