Namibia’s flag was adopted on 21 March 1990 at independence. A red diagonal band edged in white runs from lower hoist to upper fly, dividing a blue upper hoist triangle (charged with a golden sun of twelve triangular rays) from a green lower fly triangle. Blue represents the sky, Atlantic, and water; red the people’s heroism and unity; green vegetation and land; white peace. Ratio 2:3; the construction sheet standardizes the sun and band geometry and colour references.
Namibia’s banner emerged from a national competition ahead of independence and was formalised with legal specifications on 21 March 1990. The composition is dynamic: a broad red diagonal, bordered by narrow white fimbriations, cuts across a blue upper hoist triangle and a green lower fly triangle. A golden sun with twelve triangular rays rests in the blue field near the hoist.
Each element bears layered meaning. Blue stands for the sky, the Atlantic, and precious water resources. Red signifies the people—their heroism, determination, and unity in the struggle for self‑government. Green represents vegetation, agriculture, and hope for renewal. White expresses peace. The golden sun echoes the coat of arms and symbolises life and energy; its twelve rays are evenly spaced and codified.
Statutory drawings fix a 2:3 ratio; the diagonal’s width, the thickness of the white fimbriations, and the sun’s diameter and placement are defined with precision to support consistent manufacture. Protocol prescribes respectful handling, precedence, half‑masting by order, and illumination at night. The civil flag appears widely on ministries, schools, and missions; derived standards for the president and defence force add distinctive charges without altering the national colours.
The choice of a diagonal layout created instant distinctiveness among African flags, while the bright palette supports recognition on land and at sea. Since adoption the design has not been materially altered, signalling continuity in national identity and broad popular acceptance.
