COS String Concert

A poster campaign and online concert programme for the COS String Concert in Hong Kong. The posters use black-and-white close-up portraits of the performers as a base, layered with interlocking red and blue typographic blocks that lift the concert's name "COS" off the page. The online programme is mobile-first, built on a black ground that signals the concert's professionalism, with high-contrast red and blue accents on titles and interactive elements to keep on-phone reading fluid.
