What color is Dulux Chiltern White?

Dulux Chiltern White 40YY 73/028 is a light, softly muted off-white with a gentle warm-grey cast. Its low saturation keeps it from reading creamy, while the subtle yellow-based warmth prevents it from feeling stark or icy. In bright daylight, this shade can appear clean and pale; under warmer artificial light, its beige-grey undertone becomes more noticeable. It is well suited to broad wall areas in living rooms, bedrooms, and hallways, where a quiet neutral background is wanted. Pair Chiltern White with natural oak, limestone, brushed nickel, charcoal accents, or deeper mushroom-toned textiles for a layered, grounded scheme.

LRV of Chiltern White

Chiltern White has an LRV of 71.52% and refers to Light colors that reflect most of the incident 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 71.52%, 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.
