Smokestack Gray vs De Nimes
Smokestack Gray is a Benjamin Moore color while De Nimes comes from Farrow & Ball. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. At LRV 23 vs 19, Smokestack Gray will read as the brighter of the two — a 4-point gap that matters most in north-facing or low-light rooms. The tonal difference — Smokestack Gray's blue character against De Nimes's cool — becomes most visible against white trim or in morning light. With a ΔE of 2.7, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Smokestack Gray vs De Nimes in Real Spaces
6 real rooms side by side. Smokestack Gray and De Nimes 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.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Smokestack Gray has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The brightness difference is modest but present — Smokestack Gray gives the walls a little more lift.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The brightness difference is modest but present — Smokestack Gray gives the walls a little more lift.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The brightness difference is modest but present — Smokestack Gray gives the walls a little more lift.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. Smokestack Gray has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. The brightness difference is modest but present — Smokestack Gray gives the walls a little more lift.

Smokestack Gray vs De Nimes Simulated Comparison
5 simulated room previews — drag the slider on each to see Smokestack Gray on one side and De Nimes 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.
