The flag of Antigua and Barbuda is symbolic and represents various aspects of the nation's heritage and natural environment. Here's a breakdown of the flag's design and its symbolism:

1. Color Symbolism:

   • Red: Represents the energy of the people of Antigua and Barbuda and their vitality and dynamic qualities. It also represents the sun, which is a significant element for the Caribbean nation.
   • Black: Symbolizes the African ancestry of the population, and the soil of the islands.
   • Blue: Represents the Caribbean Sea that surrounds the islands.
   • White: Symbolizes the sand on the islands' beaches. It also represents hope and liberty.
   • Yellow (of the sun): Represents the dawn of a new era for the nation.

2. Other Symbols:

   • The Rising Sun: With its 7 rays, the sun represents the dawn of a new era. The number of rays can also be seen as significant because Antigua and Barbuda comprise seven parishes, though the flag's primary intention with the sun is to mark the dawn of a new era.
   • The Inverted Triangle: Represents the islands of Antigua and Barbuda themselves.

The flag was adopted on 27th February 1967 and was designed by a nationally acclaimed artist and sculptor, Sir Reginald Samuel. The adoption of the flag coincided with the country's achievement of self-governance, and it was retained upon full independence from the UK on 1st November 1981.
