Brainstorm Bronze vs Sea Mariner

Both from Sherwin-Williams's palette. Brainstorm Bronze reads as greige-grey, while Sea Mariner reads as blue-grey — two distinct hue families, not close cousins. Brainstorm Bronze (LRV 14) reflects noticeably more light than Sea Mariner (LRV 7), a difference of 8 points that becomes especially apparent in rooms with limited natural light. Brainstorm Bronze 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 21.5, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
