What color is RAL Classic Window grey?

RAL Classic Window grey RAL 7040 is a mid-tone gray with a restrained cool cast, reflected in its slightly blue-leaning #989EA1 color value. It reads clean and architectural rather than stark, offering enough depth to define a room without making walls feel heavy. In bright daylight, this shade can appear lighter and crisper, while lower or warmer light may bring out its softer gray character. Use Window grey on exterior trim, built-in cabinetry, or broad interior walls alongside white, charcoal, black metal, pale oak, and concrete finishes. It is especially effective in modern kitchens, utility spaces, and contemporary facades where a measured, practical gray is wanted.

LRV of Window grey

Window grey has an LRV of 35.91% 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 35.91%, 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.
