The Mixer Brush simulates realistic painting techniques such as mixing colors on the canvas, combining colors on a brush, and varying paint wetness across a stroke.
The Mixer Brush has two paint wells, a reservoir and a pickup. The reservoir stores the final color deposited onto the canvas and has more paint capacity. The pickup well receives paint only from the canvas; its contents are continuously mixed with canvas colors.
To load paint into the reservoir, Alt-click (Windows) or Option-click (Mac OS) the canvas. Or, choose a foreground color.
When you load paint from the canvas, the brush tip reflects any color variation in the sampled area. If you prefer brush tips of uniform color, select Load Solid Colors Only from the Current Brush Load pop-up menu in the options bar.
In the options bar, set tool options. For common options, see Paint tool options. For options unique to the Mixer Brush, see the following:
Current Brush Load swatch
From the pop-up panel, click Load Brush to fill the brush with the reservoir color, or Clean Brush to remove paint from the brush. To perform these tasks after each stroke, select the automatic Load or Clean options.
Controls how much paint the brush picks up from the canvas. Higher settings produce longer paint streaks.
A. 0% B. 100%
Specifies the amount of paint loaded in the reservoir. At low load rates, paint strokes dry out more quickly.
A. 1% B. 100%
Controls the ratio of canvas paint to reservoir paint. At 100%, all paint is picked up from the canvas; at 0%, all paint comes from the reservoir. (The Wet setting, however, continues to determine how paints mix on the canvas.)
Photoshop performs intelligent smoothing on your brush strokes. Simply enter a value (0-100) for Smoothing in the Options bar when you're working with one of the following tools: Brush, Pencil, Mixer Brush, or Eraser. A value of 0 is the same as legacy smoothing in earlier versions of Photoshop. Higher values apply increasing amounts of intelligent smoothing to your strokes.
Stroke smoothing works in several modes. Clicking the gear icon () to enable one or more of the following modes:
