Celestia Blue vs Upper West Side

Both from Benjamin Moore's palette. Celestia Blue reads as blue, while Upper West Side reads as greige-grey — two distinct hue families, not close cousins. Celestia Blue (LRV 66) reflects noticeably more light than Upper West Side (LRV 39), a difference of 27 points that becomes especially apparent in rooms with limited natural light. Celestia 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 22.0, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
