RAL 590-M vs Rockweed
RAL 590-M (RAL Effect) and Rockweed (Sherwin-Williams) come from different manufacturers. RAL 590-M reads as blue, while Rockweed reads as grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 5 vs 4 — so neither will read significantly brighter or darker than the other. A ΔE of NaN puts these firmly in different territory — two distinct design choices rather than close alternatives. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

RAL 590-M vs Rockweed Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 590-M on one side and Rockweed 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.
