Quest vs Light grey
Quest (PPG) and Light grey (RAL Classic) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 6-point LRV gap — 58 for Light grey vs 52 for Quest — means Light grey will open up a space more effectively. 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.
