2 real rooms side by side. Seeing Coastal Blue and Windmill Lane in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Windmill Lane reflects noticeably more light off the walls, making the space read more open than Coastal Blue.
