Castlegate vs Studio Mauve in Real Spaces
3 real rooms side by side. Seeing Castlegate and Studio Mauve 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. Studio Mauve reflects noticeably more light off the walls, making the space read more open than Castlegate.
Bedroom
