What represents the original 13 colonies on the American flag?

The representation of the original 13 colonies on the American flag is reflected by the 13 stripes. These stripes symbolize the first colonies that declared independence from Great Britain in 1776. Each stripe corresponds to one of the original colonies, highlighting their importance in the foundation of the United States. The alternating red and white stripes represent the courage and purity of the colonies, respectively.

While the stars in the blue background represent the current states, they do not specifically denote the original colonies. The blue background, which serves as a field for the stars, does not hold the same historical significance as the stripes. The red color reflects valor and bravery but does not directly symbolize the colonies. Thus, the 13 stripes are the specific feature of the flag that pays homage to the original 13 colonies.
