What are RAL Classic Signal black undertones?
Signal black has a blue and purple undertone based on its position in the color space. We identify undertones by isolating the pure hue (separating it from lightness and saturation), which avoids distortions caused by tints, tones, and shades.
This method is generally more reliable than judging undertones on a white background.

LRV of Signal black
Signal black has an LRV of 5.69% 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 5.69%, 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.
