Perfect Greige vs Sea Mariner

Both from Sherwin-Williams's palette. Hue-wise, Perfect Greige belongs to the greige-grey family and Sea Mariner to the blue-grey family. Perfect Greige (LRV 42) reflects noticeably more light than Sea Mariner (LRV 7), a difference of 35 points that becomes especially apparent in rooms with limited natural light. Perfect Greige runs warm while Sea Mariner is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 42.2, the contrast is hard to miss.
