Over the summer, Galerie Thomas Schulte will be presenting the  installation Red, Yellow, Green, In Time by the US-American artist Matt  Mullican. In order to categorize and order the world and how we perceive  it, Mullican has developed a subjective cosmology that translates it  into colors and pictograms and differentiates between five existential  realms of perception and cognition, that of the objective (green), the  everyday world (blue), the arts (yellow) , abstract signs (black) and  subjectivity (red). Until the end of August, in the gallery’s Corner  Space, three of Mullican’s monumental, colorful banners will be shown in  succession, announcing their symbolic message into the urban space.
