Change color of roles

I run an online academy with different levels and I want to gamify the experience and automatically add the student to the next role in the hierarchy (Jedi Knight -> Jedi Master) giving them a different color name that they can be proud of in the thread that everyone has access to and also give them access to different threads based on their new role
The gamification is the most important piece.
Giving others incentives to go through the content on the learning platform.
This feature is super useful in discord servers for many use cases.
