The Colon

The Colon is a punctuation mark that is used in very specific instances.  You should use a colon after an independent clause to indicate to the reader that a list, an apositive or a quotation will follow.  Colons are also used in the salutation of a formal letter, between hours and minutes when indicating time, to show proportions, between titles and subtitles, and between city and publisher in a bibliography.
