Roycroft Bronze Green vs Thunder Gray in Real Spaces
4 real rooms side by side. Roycroft Bronze Green and Thunder 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.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Roycroft Bronze Green brings more warmth to the space, while Thunder Gray keeps things cooler and crisper.
