Rainstorm vs RAL 830-3
Rainstorm is a Benjamin Moore color while RAL 830-3 comes from RAL Effect. These are both greys, so the question isn't which hue to choose — it's where within grey to land. With LRVs of 30 and 28, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 2.2, the difference is subtle — you'd need them side by side to reliably tell them apart. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Rainstorm vs RAL 830-3 Simulated Comparison
5 simulated room previews — drag the slider on each to see Rainstorm on one side and RAL 830-3 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.
