Blue Seafoam vs Black grey
Blue Seafoam (Benjamin Moore) and Black grey (RAL Classic) come from different manufacturers. Blue Seafoam reads as blue, while Black grey reads as blue-grey — two distinct hue families, not close cousins. The 63-point LRV gap — 69 for Blue Seafoam vs 6 for Black grey — means Blue Seafoam will open up a space more effectively. A ΔE of 68.3 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.
