Flexible Gray vs Mountain Air

Both from Sherwin-Williams's palette. Flexible Gray reads as grey, while Mountain Air reads as blue-grey — two distinct hue families, not close cousins. Mountain Air (LRV 73) reflects noticeably more light than Flexible Gray (LRV 38), a difference of 35 points that becomes especially apparent in rooms with limited natural light. Flexible Gray runs warm while Mountain Air is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 22.1, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
