Decorations (e.g., streamers, balloons, and clothing) are generally colored red, white, and blue, the colors of the American flag. Parades often are in the morning, while fireworks displays occur in the evening at such places as parks, fairgrounds, or town squares.   Independence Day fireworks are often accompanied by patriotic songs such as the national anthem ("The Star-Spangled Banner"), "God Bless America", "America the Beautiful", "My Country, 'Tis of Thee", "This Land Is Your Land", "Stars and Stripes Forever", and, regionally, "Yankee Doodle" in northeastern states and "Dixie" in southern states. Some of the lyrics recall images of the Revolutionary War or the War of 1812.   Firework shows are held in many states, and many fireworks are sold for personal use or as an alternative to a public show.
