When the OnBetterChat hook is triggered, I need to change the title color, but as I understand it, it can't be done through the data dictionary, right?
Sorry for my bad English.

Using BetterChat groups data config

[
  {
    "GroupName": "default",
    "Priority": 1,
    "Title": {
      "Text": "[]",
      "Color": "#00ffffff",
      "Size": 17,
      "Hidden": true,
      "HiddenIfNotPrimary": true
    },
    "Username": {
      "Color": "#ffff00ff",
      "Size": 17
    },
    "Message": {
      "Color": "#ffffffff",
      "Size": 17
    },
    "Format": {
      "Chat": "{Title} {Username}: {Message}",
      "Console": "{Title} {Username}: {Message}"
    }
  },
  {
    "GroupName": "Noob",
    "Priority": 4,
    "Title": {
      "Text": "[Noob]",
      "Color": "#00ffffff",
      "Size": 17,
      "Hidden": false,
      "HiddenIfNotPrimary": false
    },
    "Username": {
      "Color": "#ffff00ff",
      "Size": 17
    },
    "Message": {
      "Color": "#ffffffff",
      "Size": 17
    },
    "Format": {
      "Chat": "{Title} {Username}: {Message}",
      "Console": "{Title} {Username}: {Message}"
    }​

The player group (if any) will show as Blue , the player name will show as yellow and the text will show as white,  if the player (on my server) does not have a group (which are time based)  only the name and text will show,

I know how to create groups. I am writing my own plugin that will interact with BetterChat.
