Hi there! I was playing around with cel shading effects and edge detection following Tatsuro Ide's tutorial on cel shading. He uses a laplacian filter for the edge detection and I was wondering if there's a way of instead just painting it with a single color using a vector (Like in the image below), to saturate the color underneath those edges detected by the laplacian filter created.

So instead of just painting it black (or whatever color), using those lines to desaturate/saturate the color underneath it by a percentage:
