Yellow (2006 short film) (2006)
Yellow or Adicolor Yellow is a 2006 futuristic short film by director Neill Blomkamp, written by Terri Tatchell and Blomkamp. It was produced at the request of sportswear maker Adidas as a part of its "Adicolor" viral ads campaign, in which advertising agency Idealogue gathered seven directors, assigning a different color to each of them, and asked them to produce a feature based on their emotional and creative response to the given color, later to be distributed in the form of podcasts.
