Coliseum Marble vs Agreeable Gray in Real Spaces
2 real rooms side by side. Coliseum Marble and Agreeable 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. The distinction reads clearly at room scale, making the choice between them concrete.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
