Scumbling in colored pencil means something rather different to the dry-brush painting technique. Colored pencil scumbling is a method of shading using tiny circles, sometimes called the 'Brillo pad' technique, due to the texture of that brand of steel-wire scourer. The texture created depends on the size and pressure used to draw the circles - you can create a very smooth finish or a rough and energetic surface. Scumbling can be used to layer a single color or with alternating different colors.

You can also use a more 'concave' scumble technique to create textures. Using a sort of figure-eight or 'daisy' shaped scribble and spidery lines, rather than a round circle, creating random dark patches and a more organic looking surface.
