This is what the red, white, and blue on the US flag represent: The Continental Congress left no record to show why it chose the colors. However, in 1782, the Congress of the Confederation chose these same colors for the Great Seal of the United States and listed their meaning as follows: white to mean purity and innocence, red for valor and hardiness, and blue for vigilance, perseverance, and justice. According to legend, George Washington interpreted the elements of the flag this way: the stars were taken from the sky, the red from the British colors, and the white stripes signified the secession from the home country. However, there is no official designation or meaning for the colors of the flag.
