Blue Square vs Classic Silver

Blue SquareBehrvsClassic SilverBehrΔE 30.0Very different colors

Both from Behr's palette. Blue Square reads as blue, while Classic Silver reads as grey — two distinct hue families, not close cousins. Classic Silver (LRV 48) reflects noticeably more light than Blue Square (LRV 20), a difference of 28 points that becomes especially apparent in rooms with limited natural light. Blue Square runs blue while Classic Silver is decidedly yellow, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 30.0, 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 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
