What color is Benjamin Moore Coastline?

Benjamin Moore Coastline AF-570 is a muted blue-gray with a cool, gently weathered cast. Its medium-light depth gives walls noticeable color without making a room feel dark, while the softened saturation keeps the finish understated rather than icy. In bright daylight, Coastline can read cleaner and slightly bluer; under warmer lamps, its gray base becomes more apparent. It suits bedrooms, bathrooms, and living areas, especially alongside crisp white trim, pale oak, brushed nickel, and charcoal accents. Use it on full walls for a quiet backdrop or on cabinetry for a measured contrast against light counters.

What are Benjamin Moore Coastline undertones?

Coastline AF-570 reads as a mid-light, low-saturation blue-gray with a noticeably softened, muted character. In the supplied digital sample, the blue direction is clear, while a slight greenish bias is subtle and not strong enough to treat as a fixed undertone. Benjamin Moore describes it as “a dusty medium blue with intriguing gray undertones,” which fits its visibly blue main family being moderated by gray rather than appearing bright or pure. Warm artificial light may make its gray cast feel more noticeable, while cool daylight can help its blue character show more clearly.

LRV of Coastline

Coastline has an LRV of 33.93% 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 33.93%, 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.
