Cayman Lagoon vs Sea Emerald
Cayman Lagoon (Benjamin Moore) and Sea Emerald (Jotun) come from different manufacturers. Hue-wise, Cayman Lagoon belongs to the blue family and Sea Emerald to the blue-grey family. Their light reflectance values are nearly the same — 25 vs 26 — so neither will read significantly brighter or darker than the other. Where Cayman Lagoon leans green and blue, Sea Emerald reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 29.5 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.
