Van Dyke (Vandyke) brown, also known as Cassel earth or Cologne earth, is a deep, rich, and warm brown colour often used in painting and printmaking. Early publications on the pigment refer to it as Cassel (or Kassel) earth or Cologne earth in reference to its city of origin; however, today it is typically called Van Dyke brown after the painter Anthony van Dyck.[2]: 157
The colour was originally made from peat or soil, and has been applied as both watercolour and oil paints.[3] Today, the pigment is made by combining asphaltum-like black with iron oxide. This replicates the colour of the original iron oxide-rich earth found in Cassel and Cologne, Germany.[4]
