There are some situations where forgetfulness can be fatal as depicted in the Coimbra Color Lock campaign. When it comes to locking up dangerous animals such as certain dogs and all lions as well as oneself if scuba diving with sharks, a person will not want to leave the actual lock behind. Thanks to these vibrantly hued options, however, they will be "impossible to forget," as stated by the tag line.
The Coimbra Color Lock campaign was conceived and executed by dim&canzian, an ad agency based in São Paulo, Brazil. Art directed by Michele Dim D’Ippolito, Doda Ferrari and Caio Almeida with creative direction by Gabriel Araujo, Bruno Salgueiro, the images were illustrated by Pict Studio.
