What color is Benjamin Moore Watertown?
Benjamin Moore Watertown 818 is a medium blue with a clear cool cast and enough grayness to keep it from reading overly bright. Its moderate depth gives walls noticeable color without making a room feel heavy, especially when paired with crisp white trim. In bright daylight, Watertown can appear cleaner and slightly more open, while lower light brings out its quieter, dustier side. It suits bedrooms, bathrooms, and home offices, and also makes a considered choice for painted cabinetry or a front door. Pair it with soft white, pale gray, natural oak, brushed nickel, or warm leather accents to add contrast without competing with the blue.

LRV of Watertown
Watertown has an LRV of 22.6% 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 22.6%, 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.
