About Benjamin Moore Coastline
Coastline sits in the mid-range at LRV 34, so it shifts visibly through the day — lighter and more open in morning light, deeper and moodier after dark. Its blue undertone is the part to watch: it gets picked up by whatever sits next to it, so test it against your trim, floor and the room's main light before committing. South-facing rooms will pull it lighter and warmer, while north light cools it down.
Coastline is versatile enough for full rooms but has enough depth to anchor a space, so it suits living rooms, bedrooms and cabinetry alike. Grays like this read as a modern neutral and sit comfortably alongside both warm woods and cool metals.
