It is a vertical tricolor of green, red and yellow, with a five - pointed star in its center . There is a wide variation in the size of the central star, although it is always contained within the inside stripe . </P> <P> The color scheme uses the traditional Pan-African colors (Cameroon was the second state to adopt them). The center stripe is thought to stand for unity: red is the colour of unity, and the star is referred to as "the star of unity". The yellow stands for the sun, and also the savannas in the northern part of the country, while the green is for the forests in the southern part of Cameroon . </P>
