Shadow Blue vs Dockside Blue
Where Shadow Blue belongs to Behr's range, Dockside 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 (44 vs 43), so they'll read as similarly Medium in most lighting conditions. Shadow Blue runs blue while Dockside Blue is decidedly cool, which means they'll respond very differently to warm vs cool light sources. At ΔE 1.8, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
