Chilly Blue vs Opal Waters
Both from Behr's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Opal Waters (LRV 53) reflects noticeably more light than Chilly Blue (LRV 38), a difference of 15 points that becomes especially apparent in rooms with limited natural light. Both lean blue, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 11.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
