RGB Hex colors not respected with custom kick messages

When you try to use hex colors to kick someone from the server. It seems to not respect using ChatColor.Of. The method used works just fine with chat, but isnt respecting custom kick messages. It would only use the last letter or number in the hex code

Snippet of what i want to use:

offender.kickPlayer(RGBSupport.translateHexCodes("&#rrggbb[&#r1g1b1You were Kicked&#rrggbb]&#r2g2b2: &r" + reason, this.plugin));

Uses "&#rrggbb"
