'Sensitization to Colour' reconstructs the room where legendary Polish artist Włodzimierz Borowski (1930–2008) performed the work 'Sensitization to Colours', including objects used in the initial performance as well. The original performance, in the Od Nowa Gallery in Poznań in 1969, was only visually recorded in a few black and white photographs. Here Agnieszka Polska imagines how the performance by this key figure in the Polish avant-garde could have been staged.
