What color is Benjamin Moore Castle Gate?
Benjamin Moore Castle Gate CSP-75 is a muted mid-tone gray with a noticeable taupe cast, softened by subtle brown and beige undertones. Its low-saturation appearance keeps it from reading cold or blue, giving walls a grounded, quietly earthy look. In bright natural light, Castle Gate can appear like a softened warm gray, while evening light tends to bring out its deeper mushroom-brown side. It suits living rooms, bedrooms, and entryways where a darker neutral is wanted without the weight of charcoal. Pair it with creamy off-whites, weathered oak, linen upholstery, black metal details, or muted olive and clay accents.

LRV of Castle Gate
Castle Gate has an LRV of 25.81% 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 25.81%, 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.
