What color is RAL Classic Blue grey?

RAL Classic Blue grey RAL 7031 is a muted, medium-dark grey with a clear cool blue cast. Its low saturation keeps it grounded rather than bright, giving walls a calm slate-like presence in daylight. In cooler north-facing rooms, Blue grey can appear more distinctly blue, while warm artificial light tends to draw out its softer charcoal-grey side. It suits cabinetry, exterior trim, and feature walls particularly well, especially alongside pale oak, brushed steel, off-white plaster, or deep navy textiles. For contrast, pair this color with warm cream or muted terracotta rather than stark white.

LRV of Blue grey

Blue grey has an LRV of 16.43% and refers to Medium Dark which means that this color reflects very little 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 16.43%, 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.
