The Ink Bleeds & Blots template for After Effects allows you to create custom ink or watercolor effects. These effects can imitate ink spreading on wet paper, drops in water, and even Rorschach (inkblot) tests.
The ink effects are all done procedurally (in After Effects), so they are completely customizable. Convenient slider controls on the "Control Layer" allow you to easily change the colors, shape, softness, location, texture, and more. Control where your ink bleeds simply by editing the shape's path. It's flexible and fun to use, and you'll be returning to it for many projects to come!
