Building on Photoshop's built in mixer brush engine, we've designed these brushes to be FULL COLOR. We spent months researching, beta testing and fine tuning this method. All the brush head shapes and gradient color swatches were built from scratch. With 40 brush head shapes and 45 paint swatches, you have over 1800 different brush/color combinations.
While there are many great uses for Gradial, we think you'll really love using them for creating custom lettering. The brushes will give you an instant fluid, dimensional look to your work.
Using the included set of layer styles, you can easily customize the feel of your paint strokes to get a multitude of different looks by using pre-built adjustments. Since all the layer styles are editable, you can fine tune them even more for your specific project or create your own custom adjustments
