Provide more context on how to change colors

Need to think of a clever way to help people understand how Material You icon packs work. I'm getting lots of negative review from people who don't understand that, it's a system setting, or a launcher setting that controls it.

The supported help page might also be good for this: https://github.com/Arcticons-Team/Arcticons/wiki/Supported-Launchers

For example:
System settings > Wallpaper & Style > Color palette

How about something like this inside the app.
