Trade Chat with special color

Hello!
I need trade chat in Better Chat plugin. When somebody say "@ Sell 30 wheels for c4" this will be in blue color.
Why it is not working?

Code:

        bool OnPlayerChat(PlayerSession player, string message, bool isClanMsg = false)
        {
            if (message.StartsWith("@"))
            {
             titles.Add("[Trade]", "#C4FF00");
             playerData["Formatting"] = "{Title} {Name}<color={TextColor}>:</color> {Message}";
             playerData["ConsoleFormatting"] = "{Title} {Name}: {Message}";
            }

 

You must put that part in at a later position. That is too early. Do it at the place where I do it.
