What color is Behr Old Amethyst?
Behr Old Amethyst MQ5-03 is a muted midtone gray with a restrained violet-blue cast that keeps it from reading flat or purely neutral. Its low saturation gives walls a softened, slightly smoky appearance, while the cool undertone becomes more noticeable in bright daylight. In warmer evening light, Old Amethyst can appear closer to a balanced charcoal-gray with a faint purple haze. It suits bedrooms, studies, and living rooms where a deeper neutral is wanted without the heaviness of near-black paint. Pair it with crisp white trim, pale oak, brushed nickel, and charcoal textiles, or use it on cabinetry for a quiet contrast against light stone countertops.

LRV of Old Amethyst
Old Amethyst has an LRV of 24.54% and refers to Medium 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 24.54%, 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.
