If you’re like most people, you probably have a mixer brush in your Photoshop palette. This brush is used to mix colors together and can be used to create a variety of effects. To make a mixer brush in Photoshop, first open the Brushes palette and select the mixer brush. Next, click on the Edit button and change the following properties: The color of the mixer brush should be set to something dark or black. The size of the mixer brush should also be set to something small so that it can easily be blended with other colors. Finally, make sure that the Mixer Brush is enabled under Brush Settings in the Brushes palette.
