On a warm afternoon, the sky-blue looks almost illegally fresh. A black cat stretches across a white deckchair, eyes half-closed, with sea and sand glowing through the window behind. The room loosens up the moment it goes on the wall colour without effort, humour without trying too hard. It earns its keep above a bed, a kitchen counter, or a sideboard in a sun-warmed hallway, where the yellow rug catches the light and the blue does the cooling. Pair it with white-painted wood, pale linen, a rattan chair, or a stoneware lamp. Avoid stacking it next to anything sombre, fussy or competing this one wants room to breathe. Looks especially good as a clean, unframed canvas with a crisp white edge.
