Glacier Blue vs Atmosphere
Where Glacier Blue belongs to Benjamin Moore's range, Atmosphere is a Dulux color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Atmosphere (LRV 83) reflects noticeably more light than Glacier Blue (LRV 70), a difference of 13 points that becomes especially apparent in rooms with limited natural light. Glacier Blue runs blue while Atmosphere is decidedly cool, which means they'll respond very differently to warm vs cool light sources. At ΔE 2.8, 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.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
