Clover
Clover is a comprehensive solution in the form of a datapack or mod that allows you to customize name colors and pronoun selection in chat and gameplay. Both functions work independently of each other — you can set a name color without specifying pronouns or vice versa.
Your settings are managed through the /trigger clover command.

Example of pronoun display in the game:

If you need additional pronoun options, you can submit a request in the project's GitHub repository. We'll do our best to consider all suggestions!
