Pool Blue vs Waterfall

Both from Sherwin-Williams's palette. Pool Blue reads as blue, while Waterfall reads as blue-green — two distinct hue families, not close cousins. They have nearly identical light reflectance values (70 vs 71), so they'll read as similarly Light in most lighting conditions. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 5.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
