RAL 840-4 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 RAL 840-4

RAL 840-4 has an LRV of 21.39% and refers to Medium colors that reflect a lot of 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 21.39%, 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.
