Colonial Blue vs Upper West Side

Both from Benjamin Moore's palette. Hue-wise, Colonial Blue belongs to the blue family and Upper West Side to the greige-grey family. Upper West Side (LRV 39) reflects noticeably more light than Colonial Blue (LRV 35), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Colonial Blue 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 22.8, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
