Polaris vs RAL 820-2
Polaris is a PPG color while RAL 820-2 comes from RAL Effect. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. With LRVs of 41 and 42, they'll behave almost identically in terms of how much light they reflect back into a room. At ΔE 4.4, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. 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.
