Metropolitan vs Poseidon

Both from Benjamin Moore's palette. Hue-wise, Metropolitan belongs to the grey family and Poseidon to the blue family. Metropolitan (LRV 50) reflects noticeably more light than Poseidon (LRV 31), a difference of 19 points that becomes especially apparent in rooms with limited natural light. Metropolitan runs green while Poseidon is decidedly blue, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 38.7, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
