What I want to recommend today is a unity 2D shader effect that I made myself, which is mosaic or pixelation, plus a contour effect. It can be used in your 2D games.
You can adjust the main color of 2D objects
The number of pixel blocks can be adjusted
The thickness of the outline lines can be adjusted
The color and brightness of the outline lines can be adjusted
