Green Bay vs River Rouge

Both from Sherwin-Williams's palette. Hue-wise, Green Bay belongs to the blue-green family and River Rouge to the grey family. They have nearly identical light reflectance values (11 vs 12), so they'll read as similarly Dark in most lighting conditions. Green Bay runs cool while River Rouge is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 33.1, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
