Sea Mariner vs Useful Gray
Both from Sherwin-Williams's palette. Hue-wise, Sea Mariner belongs to the blue-grey family and Useful Gray to the beige-greige family. Useful Gray (LRV 59) reflects noticeably more light than Sea Mariner (LRV 7), a difference of 52 points that becomes especially apparent in rooms with limited natural light. Sea Mariner runs cool while Useful Gray is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 52.1, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
