Sea Glass vs Signal grey
Where Sea Glass belongs to Benjamin Moore's range, Signal grey is a RAL Classic color. Sea Glass reads as green-grey, while Signal grey reads as grey — two distinct hue families, not close cousins. They have nearly identical light reflectance values (33 vs 35), so they'll read as similarly Medium in most lighting conditions. The ΔE 6.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
