Gauntlet Gray vs Thunder Gray
Gauntlet Gray and Thunder Gray 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 — 17 for Gauntlet Gray vs 9 for Thunder Gray — means Gauntlet Gray 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 13.3 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Gauntlet Gray vs Thunder Gray in Real Spaces
5 real rooms side by side. Seeing Gauntlet Gray and Thunder Gray 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. Gauntlet Gray reflects noticeably more light off the walls, making the space read more open than Thunder Gray.
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. Gauntlet Gray 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. Gauntlet Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Gauntlet Gray 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. Gauntlet Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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.
