Red Umber

(No. 124)

Swatch of Michaewl Harding Green Gold oil colour

Ⓥ VEGAN

Inorganic – Red Umber is a synthetic iron oxide. I decided to make this variant shade of Burnt Umber after my observations of 16th and 17th  century paintings suggested this pigment had lighter and redder characteristics than those it assumed when manufactured in animal bladders. Raw Umber is calcinated to make the pigment, and the amount of Manganese Dioxide mixed with the Iron Oxide determines the range of undertones; my formulation is much warmer than is usual.

Colour Index PBr6
Drying Very Fast
Transparency Semi-Transparent
Lightfastness Excellent
Oil Content Average
Tint Power Average
Toxicity Non-Toxic
