Azure Tide vs Perfect Periwinkle

Both from Sherwin-Williams's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Perfect Periwinkle (LRV 23) reflects noticeably more light than Azure Tide (LRV 12), a difference of 11 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 14.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
