Color bleeding/fading, Post-Process

Hello,

I’m trying to figure out how to make a color bleeding post-process effect. I’m using post-process material to do so, but I’m having a hard time figuring out what does what. If someone could give me a hint or a direction in my search, that could be very useful.

I’d like to take the main color of the asset and leak it in a given direction. A bit like the Scene Fringe effect (chromatic aberration), but with multiple repetitions and only the main color channel (R, G or B). This will take effect on the assets in my scene, but also on the text and other stuff.

The expected result of color bleeding should look like this GIF:
color_abberation_fading

Thank you!
