* A color may be specified in the sign text by using "#" followed by a single hexadcimal digit (0-9 or a-f). These colors come from the standard Linux/IRC/CGA color set, and are shown in the sign's formspec. Any color change will remain in effect until changed again, or until the next line break. Any number of color changes in any arbitrary arrangement is allowed.
