Sea Glass vs Tranquil Dawn
Sea Glass (Benjamin Moore) and Tranquil Dawn (Dulux) come from different manufacturers. These are both green-greys, so the question isn't which hue to choose — it's where within green-grey to land. The 22-point LRV gap — 55 for Tranquil Dawn vs 33 for Sea Glass — means Tranquil Dawn will open up a space more effectively. Where Sea Glass leans green, Tranquil Dawn reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 14.5 puts these firmly in different territory — two distinct design choices rather than close alternatives. 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.
