What color is RAL Classic Signal grey?

RAL Classic Signal grey RAL 7004 is a mid-tone grey with a restrained, neutral appearance and modest saturation. Its #9A9B9B value keeps it close to an even grey, without a strong color cast competing with surrounding finishes. In bright daylight, this shade can read clean and lightly softened; under warmer indoor lighting, it may appear a little gentler rather than stark. Use Signal grey on broad wall areas, exterior trim, utility spaces, or cabinetry when you want a practical grey that does not dominate the room. Pair it with crisp white, charcoal accents, pale wood, black metal, or concrete-textured surfaces for a clear, grounded palette.

LRV of Signal grey

Signal grey has an LRV of 34.79% 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 34.79%, 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.
