Coastal Grey vs Dover Surf in Real Spaces
2 real rooms side by side. Coastal Grey and Dover Surf 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. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
