I tried different methods with the help of other Krita users, but I could not find a method that gave me the result I needed, so I am writing a request.
There is a function in Photoshop and Clip Studio called “watercolor edge”. Roughly speaking, it allows you to add a darker edge to each brush stroke without affecting the rest of the stroke color in any way.
The counterpart to this is a “layer style” when you apply a stroke that outlines the entire drawn object on the current layer.
Being able to apply a “dark edge” to every stroke would be great for stylized work.
I have attached images below that are not mine, but they nicely show the idea.

And here’s another example on hair (mine this time).
