Amethyst Sky vs Guilford Green
Both from Benjamin Moore's palette. Hue-wise, Amethyst Sky belongs to the grey family and Guilford Green to the beige-green family. Guilford Green (LRV 57) reflects noticeably more light than Amethyst Sky (LRV 32), a difference of 25 points that becomes especially apparent in rooms with limited natural light. Amethyst Sky runs red while Guilford Green is decidedly yellow, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 27.5, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
