Gallery Green vs Surf Green

Both from Sherwin-Williams's palette. Gallery Green reads as green-grey, while Surf Green reads as blue-green — two distinct hue families, not close cousins. They have nearly identical light reflectance values (22 vs 21), so they'll read as similarly Medium in most lighting conditions. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 8.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
