Iron Ore vs Thunderous
Iron Ore and Thunderous come from the same Sherwin-Williams collection. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 9-point LRV gap — 15 for Thunderous vs 6 for Iron Ore — means Thunderous will open up a space more effectively. Both share a neutral character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 17.7 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 9 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Iron Ore vs Thunderous in Real Spaces
9 real rooms side by side. Seeing Iron Ore and Thunderous 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. Thunderous reflects noticeably more light off the walls, making the space read more open than Iron Ore.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Thunderous returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Thunderous returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Thunderous returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. Thunderous returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Mudroom
In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. The LRV gap is large enough that Thunderous will make the room feel meaningfully brighter than Iron Ore would.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Thunderous returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Thunderous reflects noticeably more light off the walls, making the space read more open than Iron Ore.
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. Thunderous returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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