Put bluntly, your bedroom can carry more blue than it thinks. This one is a deep, slightly dusty mid-blue that fills the whole wall, with a single white swan sitting low and calm in it. Hung up, it does the job a painted feature wall does, but without the commitment: the room feels cooler, quieter and a bit more considered. It works best above a headboard, along a hallway, or on a narrow wall between two windows. Keep the things around it soft and pale, so linen, grey wool, pale wood, white ceramics. Don’t crowd it with busy patterns or other bold colours nearby, and don’t hang it low behind clutter, as the empty blue is the whole point. On canvas the blue reads deeper and more painterly from across the room.
