Constellation vs RAL 180-2
Where Constellation belongs to PPG's range, RAL 180-2 is a RAL Effect 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 (60 vs 58), so they'll read as similarly Light in most lighting conditions. At ΔE 1.7, 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.

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.
