Sea Green vs Tranquil Dawn
Where Sea Green belongs to Benjamin Moore's range, Tranquil Dawn is a Dulux color. Sea Green reads as green, while Tranquil Dawn reads as green-grey — two distinct hue families, not close cousins. Tranquil Dawn (LRV 55) reflects noticeably more light than Sea Green (LRV 42), a difference of 13 points that becomes especially apparent in rooms with limited natural light. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 16.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. 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.
