Cameroon
What the source says
Referenced, awaiting primary-source reviewAdopted in its present form on 20 May 1975. Red [is] the colour of unity and the star is referred to as "the star of unity"; yellow stands for the sun, and also the savannas in the northern part; green is for the forests in the southern part. The previous flag (1961-1975) had two gold stars; the 1975 redesign changed this to a single centered star when Cameroon became a unitary state.
