Hm, strange. Everything works fine for me. I've tried and are using so far green,lightgreen, lightblue,blue,grey,purple,lime,lightred,dark red and orange.
Example:
Code:
"Messages"
{
"1"
{
"default" "{Green}[Tag]{Default}Don't play alone! Join our {Lime}TeamSpeak 3 server!{Default} IP: {Olive} ts.test.com"
"type" "T"
}
}
}
Have you tried to reinstall the plugin,
