Great Grape vs RAL 580-M
Great Grape (PPG) and RAL 580-M (RAL Effect) come from different manufacturers. Great Grape reads as blue-grey, while RAL 580-M reads as blue — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 16 vs 15 — so neither will read significantly brighter or darker than the other. A ΔE of 2.9 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. 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.
