However, contrary to the agreement

However, contrary to the agreement with the museum, the artist reworked the original panel. Afterward Mack stated that he had wanted to correct the last repainting done by Uecker, who had, according to Mack, used the wrong white tone. Furthermore, Mack was no longer convinced of the advantages of using an exhibition copy.8 Thus the original light panel was repainted for at least the fifth time, which unfortunately created a visual imbalance within the artwork: there is a considerable discrepancy between the bright white color of the repainted panel and the aged, yellowish-white paint on the easel (fig. 12.6). A conservation studio9 was commissioned to produce the exhibition copy of the light panel, which should integrate harmoniously, and temporarily, into the overall structure (Erhan 2015:6-16).
