Behr Opal Waters MQ5-50 is a light, muted blue-gray with a distinctly cool cast and softened gray undertones. Its low saturation keeps it from reading overly icy, giving walls a clean, airy look without becoming stark.

It suits bathrooms, bedrooms, laundry rooms, and sunlit living areas where a pale, understated color is wanted. Pair it with crisp white trim, pale oak, brushed nickel, charcoal accents, or warm off-white textiles to give the cool color some contrast.

LRV of Opal Waters
Opal Waters has an LRV of 53.28% 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 53.28%, 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.
