The ΔE 4.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

Umbra grey vs RAL 870-M in Real Spaces
2 real rooms side by side. Umbra grey and RAL 870-M 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. The distinction reads clearly at room scale, making the choice between them concrete.

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.
