Hidden Falls vs Olympus Green

Both from Benjamin Moore's palette. Hue-wise, Hidden Falls belongs to the blue-grey family and Olympus Green to the blue-green family. They have nearly identical light reflectance values (9 vs 9), so they'll read as similarly Dark in most lighting conditions. Hidden Falls runs green and blue while Olympus Green is decidedly blue, which means they'll respond very differently to warm vs cool light sources. The ΔE 4.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
