Seashell vs Black grey
Seashell (Benjamin Moore) and Black grey (RAL Classic) come from different manufacturers. Hue-wise, Seashell belongs to the beige-yellow family and Black grey to the blue-grey family. The 73-point LRV gap — 80 for Seashell vs 6 for Black grey — means Seashell will open up a space more effectively. A ΔE of 72.3 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.
