b2.1. Use colons at the end of a complete sentence to introduce and connect new information, such as lists, tabulations, and texts. (Capitalize what follows the colon only when the word begins another complete sentence [The plan was simple: The bartender would head up to Canada, while the truck driver would go to Butte].)
b2.2. Use a colon to introduce a direct quotation of more than one sentence (Cooper said: "Every day, once a day, give yourself a present. Don't wait for it; just let it happen."). (If only one sentence, use a comma.)
