Clan tag

This is probably a stupid question but how do I change the colour of clan tags?

I have this set in config:

"Settings Clans": {
      "Display a clan tag in the chat (if Clans are installed)": true,
      "The color of the additional tag": "#FF0000, #FF3300, #FF6600, #FF9900, #FFCC00, #FFFF00, #CCFF00, #99FF00, #66FF00, #33FF00"
    }

I'm using ClansReborn, which should be fine.

I see nothing to click in the UI and no command to run. 

Thanks
