Hay Stack vs Summer Blue

Both from Benjamin Moore's palette. Hue-wise, Hay Stack belongs to the beige-yellow family and Summer Blue to the blue family. Hay Stack (LRV 81) reflects noticeably more light than Summer Blue (LRV 45), a difference of 36 points that becomes especially apparent in rooms with limited natural light. Hay Stack runs yellow while Summer Blue is decidedly blue, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 61.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
