Red Umber (series1)

Variant shade of Burnt Umber inspired as a result of bservations of 16th-17th painting, which suggested that this pigment had lighter and redder characteristics than those it assumed when manufacture in bladders, and then tubes, began a century later. Raw Umber is calcined to make this pigment, and the extent of Manganese Dioxide mixed with the Iron Oxide determines the range of undertones; here much warmer than is usual.
