is it possible to add multiple brushes Like pencil, marker, ink pen , sketch pen, etc to your concept?
it's my humble request to you if you can guide me.

I intend this project to stay “didactical” as a way to show how a coloring book app might work
A drawing engine like the one you are describing is something more complex than this project
