Cathedral Gray vs Stormy Monday
Cathedral Gray (Behr) and Stormy Monday (Benjamin Moore) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Their light reflectance values are nearly the same — 40 vs 41 — so neither will read significantly brighter or darker than the other. Both share a red character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 1.3 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cathedral Gray vs Stormy Monday in Real Spaces
2 real rooms side by side. Cathedral Gray and Stormy Monday 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.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

Cathedral Gray vs Stormy Monday Simulated Comparison
5 simulated room previews — drag the slider on each to see Cathedral Gray on one side and Stormy Monday 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.
