RAL 570-3 vs H356
RAL 570-3 (RAL Effect) and H356 (Tikkurila) come from different manufacturers. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 6-point LRV gap — 51 for H356 vs 45 for RAL 570-3 — means H356 will open up a space more effectively. A ΔE of 16.2 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 570-3 vs H356 Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 570-3 on one side and H356 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.
