What color is Benjamin Moore Platinum Gray?

Benjamin Moore Platinum Gray HC-179 is a light-to-mid gray with a muted green-gray cast visible in its #A8A9A3 color value. It has low saturation, so it reads as soft and restrained rather than sharply cool or blue-toned. In daylight, Platinum Gray can appear clean and lightly mineral, while warmer artificial lighting may bring out its faint earthy undertone. It suits living rooms, bedrooms, and hallways where a quiet neutral is wanted without the starkness of a pale white-gray. Pair it with warm white trim, natural oak, brushed nickel, charcoal accents, or soft black for a grounded, edited look.

LRV of Platinum Gray

Platinum Gray has an LRV of 39.64% and refers to Medium colors that reflect a lot of light. Why LRV is important?

Light Reflectance Value scale illustration

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 39.64%, 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.
