Montpelier vs Smokestack Gray in Real Spaces
2 real rooms side by side. Montpelier and Smokestack 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.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
