Flag of South Yemen
The Flag of South Yemen consisted of a tricolour consisting of the three equal horizontal red, white, and black bands of the National Front flag with the sky-blue chevron and a tilted red star on the left side of the hoist. The red star represented the leadership of the party, the National Front, which later became the Yemeni Socialist Party.
The flag was adopted on 30 November 1967 when South Yemen declared its independence from the British colonization until the Yemeni unification in 1990. The flag of South Yemen was the only flag from the Arab Liberation Flag family to feature the color blue.
