In MUME you can use the ANSI standard in room descriptions, keywords, whois' and virtually any text that may be edited through the local editing protocol. The Mume line-editor will however have problems handling these codes since it will not support the <esc> character that's needed for ANSI codes.
A simple explanation and some examples:
The ANSI Text style attributes is as follows "<esc>" + "[" + "<attribute>" + "m" Where <attribute> is a number between 0 and 9
The ANSI color codes are always used as follows (every character is in " ") "<esc>" + "[" + "<attribute>" + "<colour>" + "m" Where <attribute> is either 3(fg) or 4(bg) and <colour> is a value between 0 and 7.
You can also combine 2 or more styles (and/or colours) to get the wanted colour and style by separating the numbers with ;
Example: bold(1) white text(37) on blue background(44) like this "<esc>" + "[" + "1" + ";" + "3" + "7" + ";" + "4" + "4" + "m"
