Amethyst Shadow vs Swiss Blue

Both from Benjamin Moore's palette. Amethyst Shadow reads as blue-grey, while Swiss Blue reads as blue — two distinct hue families, not close cousins. Swiss Blue (LRV 53) reflects noticeably more light than Amethyst Shadow (LRV 18), a difference of 35 points that becomes especially apparent in rooms with limited natural light. Amethyst Shadow runs cool while Swiss Blue is decidedly blue, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 31.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
