For this work covering more than 1,000 square metres, artist Burghard Müller-Dannhausen did for the first time not use his self-produced colours but decided to apply Lascaux Artist. His concept of a 'wall of colour' in the tract connecting the two parts of the building continues the architecture using the means of painting. The 'wall of colour' supports orientation within the clinic building, and, with its colour rhythm, symbolises the path of recovery.
