The Comoros flag (adopted 7 January 2002) has four horizontal bands—yellow, white, red, blue—representing the islands, with a green hoist triangle bearing a white crescent and four five‑pointed stars. The crescent and stars express Islam and the four main islands (Ngazidja, Ndzuani, Mwali, Maore). Ratio 3:5; law standardises colours and emblem geometry; earlier independence‑era variants differed.
Comoros introduced its current flag on 7 January 2002 to align state symbolism with a federal constitution and to represent each major island. Four horizontal bands—yellow, white, red, blue—are set from top to bottom, while a green isosceles triangle issues from the hoist. Within the triangle, a white crescent cradles four five‑pointed stars aligned vertically.
The palette connects each band to an island: yellow for Mohéli (Mwali), white for Mayotte (Maore), red for Anjouan (Ndzuani), blue for Grande Comore (Ngazidja). The crescent and stars reflect the country’s Islamic heritage and the four principal islands. Earlier flags since independence in 1975 arranged green fields with crescent and stars in differing positions; the 2002 design added the coloured bands to signal federal balance.
Statutes establish a 3:5 ratio, the triangle’s base equal to the flag’s height, the curvature and thickness of the crescent, star size and placement, and colour references. Protocol prescribes precedence, half‑masting by order, illumination at night, and dignified retirement. The flag flies on government buildings, schools, and missions abroad and is central to national ceremonies that teach the union of islands under a single crescent.
