Coastline vs Seattle Mist

Coastline and Seattle Mist come from the same Benjamin Moore collection. Hue-wise, Coastline belongs to the blue-grey family and Seattle Mist to the greige-grey family. The 21-point LRV gap — 55 for Seattle Mist vs 34 for Coastline — means Seattle Mist will open up a space more effectively. Where Coastline leans blue, Seattle Mist reads yellow — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 21.0 puts these firmly in different territory — two distinct design choices rather than close alternatives.
