Iron Grey vs RAL 850-3
Iron Grey (Jotun) and RAL 850-3 (RAL Effect) come from different manufacturers. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 39 vs 38 — so neither will read significantly brighter or darker than the other. A ΔE of 1.7 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.
Iron Grey vs RAL 850-3 in Real Spaces
1 real room side by side. Iron Grey and RAL 850-3 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.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

Iron Grey vs RAL 850-3 Simulated Comparison
5 simulated room previews — drag the slider on each to see Iron Grey on one side and RAL 850-3 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.
