Charcoal Blue vs March Wind
Both from Sherwin-Williams's palette. Charcoal Blue reads as blue-grey, while March Wind reads as grey — two distinct hue families, not close cousins. March Wind (LRV 49) reflects noticeably more light than Charcoal Blue (LRV 6), a difference of 43 points that becomes especially apparent in rooms with limited natural light. Charcoal Blue runs cool while March Wind is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 47.5, 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 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
