Concrete grey vs Pearl mouse grey
Both from RAL Classic's palette. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Pearl mouse grey (LRV 34) reflects noticeably more light than Concrete grey (LRV 23), a difference of 10 points that becomes especially apparent in rooms with limited natural light. The ΔE 3.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

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.
