Tranquil Dawn vs Swimming
Tranquil Dawn (Dulux) and Swimming (Sherwin-Williams) come from different manufacturers. Tranquil Dawn reads as green-grey, while Swimming reads as blue — two distinct hue families, not close cousins. The 18-point LRV gap — 73 for Swimming vs 55 for Tranquil Dawn — means Swimming will open up a space more effectively. Where Tranquil Dawn leans neutral, Swimming reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 15.2 puts these firmly in different territory — two distinct design choices rather than close alternatives.
