Big Sky vs RAL 210-4
Big Sky (PPG) and RAL 210-4 (RAL Effect) come from different manufacturers. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Their light reflectance values are nearly the same — 73 vs 75 — so neither will read significantly brighter or darker than the other. A ΔE of 2.6 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.

5 simulated room previews — drag the slider on each to see Big Sky on one side and RAL 210-4 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.
