What color is Dulux Natural Slate?

Dulux Natural Slate 30BB 31/022 is a muted mid-tone grey with a subtle cool, blue-leaning cast. Its low saturation keeps it looking calm and mineral-like rather than overtly blue, making it a measured option for larger wall areas. In bright daylight, this color reads as a clean soft grey, while lower or north-facing light can bring out its cooler character. Natural Slate suits modern kitchens, home offices, and living rooms, particularly alongside pale oak, brushed nickel, white trim, and charcoal details. For a warmer contrast, pair it with linen upholstery, tan leather, or soft off-white textiles.

What are Dulux Natural Slate undertones?

LRV of Natural Slate

Natural Slate has an LRV of 29.12% 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 29.12%, 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.
