Blithe Blue vs Glimmer

Both from Sherwin-Williams's palette. Blithe Blue reads as blue, while Glimmer reads as green-white — two distinct hue families, not close cousins. Glimmer (LRV 78) reflects noticeably more light than Blithe Blue (LRV 46), a difference of 32 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 21.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
