Thunderbird vs Warm Springs

Both from Benjamin Moore's palette. Hue-wise, Thunderbird belongs to the blue family and Warm Springs to the blue-green family. They have nearly identical light reflectance values (55 vs 53), so they'll read as similarly Medium in most lighting conditions. Thunderbird runs blue while Warm Springs is decidedly green, which means they'll respond very differently to warm vs cool light sources. The ΔE 4.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
