Flag of Namibia

The flag of Namibia consists of a red diagonal band edged in two white bands with a blue upper triangle charged with an 12-ray yellow sun and green lower triangle.

The flag was adopted on 21 March 1990 upon independence from South Africa. During apartheid rule, it used the South African orange-white-blue tricolor.

Design
The National Symbols Sub-Committee received 870 entries for the national flag. Six designs were short-listed; this was reduced to three, those of three Namibians – Theo Jankowski of Rehoboth, Don Stevenson of Windhoek and Ortrud Clay of Lüderitz. These three designs were combined to form the Namibia national flag, adopted unanimously on 2 February 1990 by the Constituent Assembly. The three designers were publicly acknowledged by judge Hans Berker, the chairman of the subcommittee, at the unveiling ceremony on 9 March 1990.

However, two other claims were made – South African Frederick Brownell claimed that he had designed the flag in his role as South African State Herald. The other claimant was Briton Roy Allen, who claimed that the flag design was the result of a competition run by Hannes Smith of the Windhoek Observer, and that he had won.

It is one of the few national flags incorporating a diagonal line, with other examples including the DR Congo, Tanzania, Trinidad and Tobago, and Brunei.

Colours
The colours of the Namibian flag are described in the Government Gazette. This document also details construction of the Presidential flag. The tone or specific shade for white has not been specified.

Symbolism
The chairman explained the symbolism of the flag's colours as follows:
 * Red – represents Namibia's most important resource, its people. It refers to their heroism and their determination to build a future of equal opportunity for all.
 * White – represents peace, unity, tranquility, and harmony.
 * Green – symbolises vegetation and agricultural resources.
 * Blue – represents the clear Namibian sky and the Atlantic Ocean, the country's precious water resources and rain.
 * Golden-yellow sun – life and energy. The golden-yellow colour represents wealth of the country.
 * The twelve rays of the sun – represents the twelve ethnicities of Namibia, which make up most of the Namibian population, which are divided into four main groups of three.
