There used to be a lovely webpage on fxguide forum that explained all the blend modes. It’s not there anymore but here’s a kids book that might help
This is such a great book. Not as simple to have come up with this as it looks.
We recently got Game Builder Garage in our house. It is the only switch game not under the one hour screen time limit. So much logik involved.
I found that he has a Kickstarter for this. On his website he has a digital version you can play with.
I hope this does well.
