In a room
Passive is a light gray with a subtle green direction that can calm a bedroom, office, kitchen, or bath. It can complement white, charcoal, pale wood, and blue-green accents, though pink-beige floors may make the coolness more apparent. Natural exposure is important: reflected greenery or cool sky can shift the balance. Move a sample board around the room and review it with permanent finishes before choosing a trim white or committing to every wall.
