Echo vs Signal White
Echo is a PPG color while Signal White comes from RAL Classic. Echo reads as green, while Signal White reads as white — two distinct hue families, not close cousins. At LRV 85 vs 77, Signal White will read as the brighter of the two — a 8-point gap that matters most in north-facing or low-light rooms. At ΔE 7.3, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
