Mountain Air vs Red Bay

Both from Sherwin-Williams's palette. Hue-wise, Mountain Air belongs to the blue-grey family and Red Bay to the pink-red family. Mountain Air (LRV 73) reflects noticeably more light than Red Bay (LRV 9), a difference of 64 points that becomes especially apparent in rooms with limited natural light. Mountain Air runs cool while Red Bay is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 69.0, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
