A datapack mostly for personal use on my server, but I figured it may serve as a base for other people. The datapack automates the creation of color based teams with the right colors and prefixes. Commonly needed settings are easily changed through the menu I implemented.

To be used with my custom emoji texturepack


Run the following function to create the teams:
/function peach:teams/teamsetup

Use this to access the menu again, if you need it:
/function peach:teams/teammenu

You can either randomly join a team through the menu or join a team manually by typing
/team join OrangeTeam [​your name here]

Replace Orange with any of the following options:
Red
Pink
Orange
Yellow
Lime
Cyan
Purple
