The Ps Mixer Brush tool is designed for painting with the ability to blend colors on the image. It consists of the brush itself and a paint reservoir. When painting, paint is drawn from the reservoir depending on the specified parameters. At the brush tip, paint from the reservoir can mix with the canvas paint.

You can change the brush color using the Color, Swatches, or Color Wheel panels, or by clicking the image with the Eyedropper tool. To pick a color from the image, press and hold the I key, then select the color with the Eyedropper tool. When you release the hotkey, the painting tool becomes active again.

The basic tool settings are displayed in the Tool Options panel above the Image Window. To access the full list of parameters, click the tool icon in the Tool Options panel (or press F5), or right-click the image. To set the parameter values, enter a numerical value in the input field or move the slider.
