Mouse grey vs Iron Ore
Mouse grey (RAL Classic) and Iron Ore (Sherwin-Williams) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 12-point LRV gap — 18 for Mouse grey vs 6 for Iron Ore — means Mouse grey will open up a space more effectively. A ΔE of 17.8 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Mouse grey vs Iron Ore in Real Spaces
3 real rooms side by side. Seeing Mouse grey and Iron Ore in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Mouse grey reflects noticeably more light off the walls, making the space read more open than Iron Ore.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Mouse grey returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Mouse grey returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Mouse grey vs Iron Ore Simulated Comparison
5 simulated room previews — drag the slider on each to see Mouse 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.
