What color is Behr Bellflower Blue?
Behr Bellflower Blue M540-1 is a very light blue-gray with a cool, airy cast and a softly muted finish. Its pale value keeps it from reading overly colorful, so it can look nearly white at a glance while still giving walls a noticeable blue tint. In bright daylight, Bellflower Blue appears clean and lightly frosted; in lower light, its gray side becomes more apparent. It suits bedrooms, bathrooms, and laundry rooms where a crisp but not stark backdrop is wanted. Pair it with soft white trim, pale oak, brushed nickel, charcoal accents, or deeper slate-blue textiles for contrast.

What are Behr Bellflower Blue undertones?
Bellflower Blue is a near-white, near-neutral neutral off-white. Its chroma is so low that assigning a specific hue-based undertone would be misleading. Because it is close to neutral, nearby surfaces and the color of the light can noticeably change how warm or cool it appears.

LRV of Bellflower Blue
Bellflower Blue has an LRV of 80.07% 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 80.07%, 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.
