What color is RAL Classic Concrete grey?
RAL Classic Concrete grey RAL 7023 is a muted mid-tone grey with a noticeable olive-beige cast rather than a blue or charcoal lean. Its softened, low-saturation character gives walls a grounded look without making a room feel overly dark. In cool daylight, this shade can read as a restrained green-grey, while warmer bulbs bring out its earthy, slightly khaki side. Use Concrete grey on full walls, built-in cabinetry, or exterior details alongside warm white, black metal, natural oak, stone, and linen textiles. It is especially effective in kitchens, entryways, and workspaces where a neutral needs more depth than a standard pale grey.

What are RAL Classic Concrete grey undertones?
Concrete grey is a midtone, very muted olive-brown. The HEX sample has a subtle yellow bias, but its low chroma turns that hue into a neutral-looking color rather than a clear yellow. Warm bulbs can make it look creamier or more golden, while cool daylight may mute that warmth and pull it closer to beige or greige.

LRV of Concrete grey
Concrete grey has an LRV of 23.2% and refers to Medium colors that reflect a lot of 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 23.2%, 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.
