Umbra grey vs Iron Ore
Where Umbra grey belongs to RAL Classic's range, Iron Ore is a Sherwin-Williams color. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Umbra grey (LRV 10) reflects noticeably more light than Iron Ore (LRV 6), a difference of 4 points that becomes especially apparent in rooms with limited natural light. The ΔE 4.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Umbra grey vs Iron Ore in Real Spaces
5 real rooms side by side. Umbra grey and Iron Ore 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. The brightness difference is modest but present — Umbra grey gives the walls a little more lift.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Umbra grey reads slightly lighter here — a subtle but real difference in how open the space feels.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. Umbra grey reads slightly lighter here — a subtle but real difference in how open the space feels.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The brightness difference is modest but present — Umbra grey gives the walls a little more lift.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Umbra grey reads slightly lighter here — a subtle but real difference in how open the space feels.

Umbra grey vs Iron Ore Simulated Comparison
5 simulated room previews — drag the slider on each to see Umbra grey on one side and Iron Ore 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.
