Colouring Book App

Hello everybody, Phaser noob here.

I am planning to make a colouring book application using Phaser 3. Can someone perhaps give me some pointers as to where to start with this project? I was thinking of using the GameObjects.Graphics class but perhaps someone can advise me differently.

Any help or advice would be appreciated.

Thanks

https://labs.phaser.io is a good place to look for inspiration.

Perhaps:

https://labs.phaser.io/view.html?src=src/game%20objects/graphics/multiple%20stroke%20rects.js

Thanks, Jens, that is very helpful!
