The Mixer Brush features the ability to paint with unlimited multiple colors f8- and 16-bit RGB). For example, photographic camera-captured imagery can be a paintbrush. Only the pixels that form the edge of the tip shape actually paint to the image. This feature is primarily used in concert with the Bristle Tips. In this case, the complex tip shapes dynamically generated by the current bristle behavior form the mask through which any visible colors are painted to the image.

John begins by going over some important brush tips that many artists are unaware of: bristle, erodible, and airbrush tips. He talks about how to customize the brushes and use them to mimic natural bristle brushes, chalk, and spray paint.
