There's one last setting in the Color Dynamics palette called "Purity." This is a setting for moving away from or toward even RGB values. The default zero purity leaves your colors as they are. Increasing the value leaves the dominant color alone and decreases the secondary and tertiary values. For example, a color consisting of 255,150,150 will fall off to 255,0,0 at a purity setting of 100 percent, while a setting of -100 percent will give you a color of 255,255,255. The example below show the original, the 100 percent and the -100 percent Purity values.

Purity can also affect the individual jitter settings by forcing them to conform to a certain range of values.
Next time around we'll take a look at adding pre-defined textures to our strokes.
