Companies have been able to copyright colours with the German Patent Office since 1995, as part of their trademarks. Use of those colours by anyone else is a punishable offence. This interaction between aesthetics and capitalism has been highlighted by Rozbeh Asmani in his long-term project Colourmarks. The uncomfortable connection between colours and commercial interests is expressed in exhibition titles such as Besetzte Farben (Occupied Colours, gkg Bonn, 2016) and Wem gehört die Farbe? (Who Owns the Colours?, Museum Pfalzgalerie Kaiserslautern, 2018). In addition to his publication 72 Colourmarks, part of this project, major attention was attracted by his poster campaigns on 60 advertising pillars in Cologne (2017) and on 150 advertising pillars in Düsseldorf (2019).
