Colours make the map: they affect the map’s materiality, content, and handling. With a wide range of approaches, 14 case studies from various disciplines deal with the colouring of maps from different geographical regions and periods. Connected by their focus on the (hand)colouring of the examined maps, the authors demonstrate the potential of the study of colour to enhance our understanding of the material nature and production of maps and the historical, social, geographical and political context in which they were made.
