Scumbling As It Applies to Glazing

For many painters the word “scumble” indicates a thin, brushy application of paint applied with a dry brush––and that is an accurate use of the word.

Scumble, however, can also refer to a thin layer of opaque or semiopaque paint applied over other colors, and it’s the second definition that applies to glazing.

The effect of scumbling with white is threefold:

  1. It lightens values.
  2. It lowers chroma, thereby making the underlying color less intense.
  3. It slightly cools the temperature of the underlying color.

 

A scumble also inserts a degree of opacity, creating an excellent base for subsequent layers of transparent, glazed color.
