RAL 660-6 vs V356
RAL 660-6 (RAL Effect) and V356 (Tikkurila) come from different manufacturers. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 47 vs 48 — so neither will read significantly brighter or darker than the other. A ΔE of 12.3 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 660-6 vs V356 Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 660-6 on one side and V356 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.
