What color is Benjamin Moore Constellation?
Benjamin Moore Constellation AF-540 is a light blue-gray with a cool, lightly misted appearance and a faint blue-green cast. Its high value keeps it airy on broad walls, while the muted saturation prevents it from reading overly sweet or icy. In north-facing rooms, Constellation may lean crisper and more gray-blue; warmer daylight and incandescent lighting can bring out its softer greenish undertone. It suits bedrooms, bathrooms, and quiet living areas, especially alongside white oak, pale limestone, brushed nickel, and clean white trim. For more contrast, pair this color with charcoal accents or deep navy textiles rather than heavily yellowed creams.

LRV of Constellation
Constellation has an LRV of 72.73% and refers to Off‑White colors that reflect a lot of light. Why LRV is important?
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 72.73%, 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.
