Chicago Blues vs Upper West Side

Both from Benjamin Moore's palette. Hue-wise, Chicago Blues belongs to the blue family and Upper West Side to the greige-grey family. Upper West Side (LRV 39) reflects noticeably more light than Chicago Blues (LRV 18), a difference of 21 points that becomes especially apparent in rooms with limited natural light. Chicago Blues runs blue while Upper West Side is decidedly red, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 41.9, the contrast is hard to miss.
