How to randomize color

Quickly lay down varying colored strokes using the same brush. I’ve found this really fun to use when playing with Radial Symmetry. Set a range for the hue, saturation, and luminance of the active color.

In some of the versions of SketchBook, you can also apply randomize to brush attributes. For more information, check out Randomize.
