Three things it does fast: ground warm rust, sharpen walnut, wake living room. The colour sits right in the middle of the warm end of the spectrum, so a room with wood, leather or clay-painted walls suddenly looks like it was styled around it rather than furnished by accident. The humour does the rest people smile before they read it. Hang it above a record shelf, a sideboard or a low console, at eye level where someone standing will catch the sunglasses. Pair it with warm wood, tan leather, ribbed velvet, rust or mustard cushions and a lamp on a warm bulb. Don’t drop it into a cool grey scheme or bury it in a wall of tight black-and-white photography the warmth needs a bit of breathing room. Printed on premium fine-art paper, framed or unframed.
