Blue Sky vs Vermilion

Both from Sherwin-Williams's palette. Hue-wise, Blue Sky belongs to the blue family and Vermilion to the pink-red family. Blue Sky (LRV 58) reflects noticeably more light than Vermilion (LRV 5), a difference of 53 points that becomes especially apparent in rooms with limited natural light. Blue Sky runs cool while Vermilion is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 82.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
