- The colors must respect the [RGB](https://en.wikipedia.org/wiki/RGB_color_model) concept.
- You should be able to specify a single or a set of letters you want to be colored (use your imagination for this one).
- If the letter isn't specified, the whole `string` should be colored.

- Each Client must have an user name.
- Clients must be able to send messages to the chat.
- Messages sent, must be identified by the time that was sent and the user name of who sent the message.
- If a Client joins the chat, all the messages sent to the chat must be uploaded to the new Client.
- If a Client joins the chat, all the previous messages sent to the chat must be uploaded to the new Client.
- If a Client connects to the server, the rest of the Clients must be informed by the server that the Client joined the group.
- If a Client exits the chat, the rest of the Clients must be informed by the server that the Client left.
- All Clients must receive the messages sent by other Clients.
