Key Lime vs Tranquil Dawn
Key Lime (Benjamin Moore) and Tranquil Dawn (Dulux) come from different manufacturers. Hue-wise, Key Lime belongs to the green-yellow family and Tranquil Dawn to the green-grey family. The 16-point LRV gap — 71 for Key Lime vs 55 for Tranquil Dawn — means Key Lime will open up a space more effectively. Where Key Lime leans green, Tranquil Dawn reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 32.5 puts these firmly in different territory — two distinct design choices rather than close alternatives.

5 simulated room previews — drag the slider on each to see Key Lime on one side and Tranquil Dawn on the other.
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.
