Eclipse vs RAL 820-4
Eclipse is a Benjamin Moore color while RAL 820-4 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. At LRV 23 vs 20, RAL 820-4 will read as the brighter of the two — a 3-point gap that matters most in north-facing or low-light rooms. At ΔE 5.0, 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.

Eclipse vs RAL 820-4 Simulated Comparison
5 simulated room previews — drag the slider on each to see Eclipse on one side and RAL 820-4 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.
