Christian Louboutin shoes have red-lacquered soles. Wolf ovens have red knobs. Apple cords are white. My personal favorite, Robert Graham shirts have bright colors, unusual textiles, embroidered elements and distinctive flip cuffs. And “Knowledge Wisdom Truth” is sewn into each garment, sometimes visibly and sometimes in a hidden way.
Signature design elements, if executed properly, protected legally and used consistently can create strong brand recognition while dissuading competitors from imitation and legal infringement.
