Half Moon Crest vs Tempest

Both from Benjamin Moore's palette. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Half Moon Crest (LRV 51) reflects noticeably more light than Tempest (LRV 20), a difference of 31 points that becomes especially apparent in rooms with limited natural light. Half Moon Crest runs green while Tempest is decidedly purple, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 27.7, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
