811-2 had been withdrawn just before its scheduled auction at Christie's on June 29, 2016, lot 15. I discussed it as follows in 2016 :
During the first three decades of his career Gerhard Richter manages a continuous improvement of his control of colors. He has no equivalent in his strategy to use simultaneously the whole color spectrum in his abstract art.
He belatedly recognized a similarity with Rothko but without sharing the spiritual quest. Both chose large formats that wrap the viewer into their mental world. Richter's dissolution of multiple iridescent colors in a rigorous arrangement without lines meets a composition plan that may evoke Zao Wou-Ki.
Richter's squeegee offers new possibilities of composition. In 1994 he reaches the culmination of his art by using the extreme fluidity of his oil paint, obtaining a transparency of the layers that evokes the Zen art by Gaitonde. The artist knows that his wide squeegee could generate chance but in fact his skilled hand retains a full control of his art.
Richter would like also that his art is not influenced by emotion. However it is no coincidence that his most spectacular and most balanced abstract works were produced in 1994 in a time of joy and happiness : he had just decided to stop teaching and will marry his student Sabine, younger by 37 years.
