Cornwall Slate vs Frosted Fern in Real Spaces
2 real rooms side by side. Cornwall Slate and Frosted Fern 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. Frosted Fern reflects noticeably more light off the walls, making the space read more open than Cornwall Slate.
