This comprehensive catalogue is the first publication dedicated to the original Colour Charts, both those created in 1966 and those made in the '70s after a five-year hiatus. Featuring new essays by Dietmar Elger, head of the Gerhard Richter Archive; Hubertus Butin, curator and author of several key texts on Richter; and Jaleh Mansoor, professor at the University of British Columbia, whose research concentrates on modern abstraction and its socioeconomic implications, this is a handsome tribute to one of Richter's most groundbreaking bodies of work.
