what does blue signify in flag
âThe colors of our flag signify the qualities of the human spirit we Americans cherish,â Reagan said. âRed for courage and readiness to sacrifice; white for pure intentions and high ideals; and blue for vigilance and justice.â. The significance behind the flagâs design is more commonly known than that of its colors. The 50 stars stand for Americaâs 50 states, while the 13 red and white stripes represent the 13 colonies. But thereâs also a lesser-known interpretation for the Stars and Stripes.
