Blissful Blue vs Cosmos
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. Blissful Blue (LRV 56) reflects noticeably more light than Cosmos (LRV 38), a difference of 18 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 12.6, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
