Smoke vs RAL 820-1
Where Smoke belongs to Benjamin Moore's range, RAL 820-1 is a RAL Effect color. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. They have nearly identical light reflectance values (56 vs 57), so they'll read as similarly Light in most lighting conditions. The ΔE 4.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Smoke vs RAL 820-1 Simulated Comparison
5 simulated room previews — drag the slider on each to see Smoke on one side and RAL 820-1 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.
