Book review: Rainbows, Halos, Dawn and Dusk

Book review by Alex Murrell.  This book is the fruit of several years of research while Johannes Kuhl was leader of the Natural Science Section and the Research Institute at the Goetheanum.  Several international exhibitions on colour between 2010 and 2020 demonstrated the contribution of Goethe’s approach to modern scientific discoveries about colour.  The book also contains biographical insights into Goethe which many people have intuited, but not described so clearly until now.
