ChatColor

I’m not sure if this is super helpful; but I’m pretty sure there is a resource somewhere for Skript that allows you to create gradients with a function. You could try and format a player’s chat message using said function to do something like that.

Split the text at “”, then apply a colour code

Exactly what I said.
Splitting a string at “” will isolate each character, then just loop through and apply colours

Then join and youre done

If you dont know the basics of skript, look at some tutorials. This is a thread for help, not a code-request

Well thats a different plugin than skript, so this is not the place for help with that..
