For more than ten years, the celebrated artist Per Arnoldi of Copenhagen has been working together with the world famous London architect Norman Foster. Arnoldia (TM)s contributions range from posters of Fostera (TM)s buildings to targeted chromatic interventions in interior spaces to the complex total "chromatic concepta for a massive new structure. His color choices serve to create atmosphere and also guide the user clearly through the space. This book provides systematic and detailed documentation of this entire collaborative spectrum. Projects include: the Commerzbank in Frankfurt, the Reichstag in Berlin, the Imperial College in London, HM Treasury in London, the National Police Monument in London, the Arag Tower in DA1/4sseldorf, the World Port Center in Rotterdam, and Decauxa (TM)s headquarters in London. The photographs were taken specially for this book to capture the specific qualities of the interplay between space and color.
