Atmosphere vs Byte Blue
Where Atmosphere belongs to Dulux's range, Byte Blue is a Sherwin-Williams color. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Atmosphere (LRV 83) reflects noticeably more light than Byte Blue (LRV 68), a difference of 15 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 3.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Atmosphere vs Byte Blue in Real Spaces
1 real room side by side. Atmosphere and Byte Blue are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Atmosphere will make the room feel meaningfully brighter than Byte Blue would.

Atmosphere vs Byte Blue Simulated Comparison
5 simulated room previews — drag the slider on each to see Atmosphere on one side and Byte Blue on the other.
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.
