What color is Behr Undine?
Behr Undine M450-4 is a light, muted blue-green with a soft aqua cast and a gently cool character. Its medium-light depth gives walls noticeable color without making a room feel dark or overly saturated. In bright natural light, Undine reads cleaner and slightly bluer, while lower or warmer lighting can bring out more of its green-gray softness. It suits bathrooms, bedrooms, laundry rooms, or covered porch ceilings, especially alongside crisp white trim, pale oak, woven natural fibers, and brushed nickel. For a more grounded palette, pair this shade with charcoal accents or deep navy textiles.

LRV of Undine
Undine has an LRV of 43.2% and refers to Light Medium colors that reflect half of the incident 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 43.2%, 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.
