The proportions of Gabon’s flag are 3:4. This uncommon flag ratio, which is enshrined by Gabonese law, is shared by the flags of only three other countries – Democratic Republic of the Congo (some sources state that the proportions are 2:3), Papua New Guinea and San Marino. Furthermore, the country’s flag does not utilize the green, yellow and red colors of the Pan-Africanist movement, in contrast to its neighboring countries. Unlike other former French colonies in Africa, the flag consists of a horizontal tricolour, rather than a vertical one modeled after the flag of France.
