This November, Sotheby's is honored to announce that Mark Rothko's Blue Over Red, created in the critical year of 1953, will appear as a highlight of our Contemporary Art Evening Auction in New York. In this episode of Expert Voices, Sotheby’s Chairman Lisa Dennison examines the inspiration behind Rothko’s masterpiece and explores his pioneering approach to abstraction. Executed in a richly saturated palette of orange, red and yellow, dramatically offset by a luminous blue band, Blue Over Red exemplifies the signature radiance of Rothko’s works.
