Coastline vs River Silt
Coastline and River Silt come from the same Benjamin Moore collection. Hue-wise, Coastline belongs to the blue-grey family and River Silt to the greige-grey family. The 13-point LRV gap — 34 for Coastline vs 21 for River Silt — means Coastline will open up a space more effectively. Where Coastline leans blue, River Silt reads red — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 20.1 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
