Watercolor splashes

Hello!

I am making a grease pencil animation with a moving paintbrush.
I want the paintbrush to splash watercolor in and there but can’t really find a way to make those splashes.

I was thinking of making them in Krita and then animate them in blender but I was interested in doing the whole thing in Blender.

Any ideas?

EDIT I found this: Watercolor like shader

Thanks!
