Calypso Blue vs Loch Blue
Where Calypso Blue belongs to Behr's range, Loch Blue is a Sherwin-Williams color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. They have nearly identical light reflectance values (14 vs 16), so they'll read as similarly Dark in most lighting conditions. Calypso Blue runs blue while Loch Blue is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 4.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
