If you want to create a graphical prefix for your channels and show it in chat you have to follow this tutorial.
An example that shows the ARCADE prefix for the Arcade channel
You just have to set this in your format configuration, (for example in the format/arcade.yml file of ChatControl Red):
Obviously you have to use your own font_image name instead of arcade, this is just an example.
Text effects
Normally the ItemsAdder text effects don't work with ChatControl Red.
But if you add this to your rules folder of ChatControl Red, they will work. (I put this in global.rs).
