Pebble grey vs RAL 840-3
Pebble grey (RAL Classic) and RAL 840-3 (RAL Effect) come from different manufacturers. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. Their light reflectance values are nearly the same — 45 vs 46 — so neither will read significantly brighter or darker than the other. A ΔE of 2.2 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Pebble grey vs RAL 840-3 in Real Spaces
1 real room side by side. Pebble grey and RAL 840-3 are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

5 simulated room previews — drag the slider on each to see Pebble grey on one side and RAL 840-3 on the other.
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.
