Shadow Gray vs Thundercloud Gray
Shadow Gray and Thundercloud Gray come from the same Benjamin Moore collection. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. The 11-point LRV gap — 50 for Thundercloud Gray vs 40 for Shadow Gray — means Thundercloud Gray will open up a space more effectively. Both share a blue character, which means they'll respond to light and surrounding materials in similar ways. ΔE 7.6 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Shadow Gray vs Thundercloud Gray in Real Spaces
2 real rooms side by side. Shadow Gray and Thundercloud Gray 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.
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. Thundercloud 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. Thundercloud 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.
