Excalibur Gray vs Guilford Green
Both from Benjamin Moore's palette. Excalibur Gray reads as blue-grey, while Guilford Green reads as beige-green — two distinct hue families, not close cousins. Guilford Green (LRV 57) reflects noticeably more light than Excalibur Gray (LRV 41), a difference of 16 points that becomes especially apparent in rooms with limited natural light. Excalibur Gray runs cool while Guilford Green is decidedly yellow, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 25.1, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
