Burnt Umber is used in mixtures as a darkener of other colours, for making very dark earthy greens in mixtures with Phthalo Green or Chromium Green Oxide and in mixtures with reds to make deep Burgundy shades of colours. This works especially well when using transparent cool reds such as Primary Red or Matisse Rose Madder. These reds give warmth to the Burnt Umber and make colours that are very good for making shadows in skin while avoiding too much brown in the skin tone. Adding Ultramarine Blue to these dark Burgundies makes for rich earthy shadow colours in landscapes and for the deepest shadows in folds of red and purple drapes.
