Calypso Blue vs Harbor Side Blue
Both from Benjamin Moore's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Harbor Side Blue (LRV 40) reflects noticeably more light than Calypso Blue (LRV 18), a difference of 22 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 22.6, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
