What color is Little Greene Celestial Blue?

Little Greene Celestial Blue 101 is a muted blue-green with a soft grey cast, giving it a light, weathered appearance rather than a bright aquatic look. Its gentle green undertone becomes more noticeable in daylight, while lower or warmer light can draw out its quiet grey quality. This shade suits bathrooms, bedrooms, and north-facing sitting rooms where a pale color with visible depth is wanted. Pair Celestial Blue with chalky off-whites, warm stone tones, pale oak, or brushed nickel for a restrained, lived-in finish. It is particularly effective across full walls or on fitted cabinetry, where its low saturation keeps larger surfaces from feeling overly cool.

What are Little Greene Celestial Blue undertones?

Celestial Blue 101 reads as a mid-light, highly muted blue-green with a soft greyed character rather than a clear, bright blue. In the supplied digital sample, the visible color leans subtly toward green, though the bias is restrained and may shift with surrounding colors and lighting. Little Greene’s official undertone description was not available in the provided source, so no manufacturer undertone claim can be confirmed here. Warm artificial light may bring out its muted, slightly green cast, while cooler daylight can make it appear a little cleaner and more blue-grey.

LRV of Celestial Blue

Celestial Blue has an LRV of 43.08% and refers to Light Medium colors that reflect half 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 43.08%, 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.
