Chiswell Blue vs Upper West Side

Both from Benjamin Moore's palette. Hue-wise, Chiswell Blue belongs to the blue-grey family and Upper West Side to the greige-grey family. Upper West Side (LRV 39) reflects noticeably more light than Chiswell Blue (LRV 30), a difference of 10 points that becomes especially apparent in rooms with limited natural light. Chiswell 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 17.5, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
