Galactica vs Atmospheric
Galactica (PPG) and Atmospheric (Sherwin-Williams) come from different manufacturers. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. The 3-point LRV gap — 70 for Galactica vs 67 for Atmospheric — means Galactica will open up a space more effectively. A ΔE of 1.2 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Galactica vs Atmospheric Simulated Comparison
5 simulated room previews — drag the slider on each to see Galactica on one side and Atmospheric 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.
