What color is Behr Rock Crystal?
Behr Rock Crystal MQ3-28 is a light, softly muted gray with a barely perceptible warm blush cast rather than a stark blue-gray edge. Its low saturation keeps walls looking quiet and even, especially in bedrooms, hallways, or open living areas where stronger grays can feel heavy. In bright daylight, Rock Crystal reads as a clean pale gray; under warmer lamps, its subtle pink-beige influence becomes a little more apparent. Pair it with crisp white trim for gentle contrast, or bring in pale oak, linen upholstery, and brushed nickel for a restrained, natural palette. This shade is especially effective on broad wall surfaces where its delicate undertone can add softness without calling attention to itself.

LRV of Rock Crystal
Rock Crystal has an LRV of 60.22% and refers to Light colors that reflect most 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 60.22%, 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.
