Sometimes it's not easy to follow the chat when everything is in white text. Before we actually read the message we have to read [the type of chat] [clan tag] nickname: then finally message. Game can and does make it easier for us sometimes - it uses light-blue colour to mark our own messages (then everything EXCEPT message is light blue), and does the same with all the other colours.
My suggestion is - figure out some colour and make chat always be divided into all the information in some colour + the message in white, as it is with friends etc.
