What color is Benjamin Moore Secret?
Benjamin Moore Secret AF-710 is a muted mid-tone gray with a subtle green-olive cast. Its low saturation keeps it grounded and neutral-looking, though the green undertone becomes more noticeable beside crisp white trim or cool blue-grays. In bright daylight, Secret can read as a weathered stone gray, while warmer lamps draw out its soft khaki warmth. It suits living rooms, bedrooms, and studies where a deeper neutral is wanted without the heaviness of charcoal. Pair it with warm whites, aged brass, natural oak, linen, and dark brown wood for a relaxed, layered interior.

LRV of Secret
Secret has an LRV of 25.88% 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 25.88%, 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.
