In a public/private chatroom, the color of a text message can be set to any available color other than black. To do this, click on the chat color icon at the top of the chatroom. On the Color popup, using the dropdown selection list, choose the color of your choice, and click on the Save button. Now, if you type a message and send it in the chatroom, it will be appear colored as you had set up.
Note: Only that user’s message will appear colored who had specifically changed the color settings as explained above. The color of text messages is black by default.
