2 real rooms side by side. Seeing Buttermilk and Purbeck Stone 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. Buttermilk reflects noticeably more light off the walls, making the space read more open than Purbeck Stone.
