Signal red vs Azure blue
Signal red and Azure blue come from the same RAL Classic collection. Their light reflectance values are nearly the same — 11 vs 12 — so neither will read significantly brighter or darker than the other. A ΔE of 78.1 puts these firmly in different territory — two distinct design choices rather than close alternatives.
Signal red vs Azure blue Color Comparison
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.
