Prussian Blue vs St. Bart's
Where Prussian Blue belongs to PPG's range, St. Bart's 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 (19 vs 18), so they'll read as similarly Dark in most lighting conditions. At ΔE 2.7, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.
