Stormy Monday vs Flagstone
Where Stormy Monday belongs to Benjamin Moore's range, Flagstone is a PPG color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. They have nearly identical light reflectance values (41 vs 41), so they'll read as similarly Medium in most lighting conditions. At ΔE 1.7, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Stormy Monday vs Flagstone in Real Spaces
2 real rooms side by side. Stormy Monday and Flagstone 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
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

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.
