The flag of Eritrea is dominated by a red isosceles triangle based on the hoist-side pointed toward the fly-side and then divided into two right triangles. The upper triangle is green and the lower triangle is blue with a yellow vertical olive branch encircled by an olive wreath centered on the hoist side of the triangle. The shape of the red triangle broadly mimics the shape of the country. The green stands for the agriculture and livestock of the country, blue for the bounty of the sea, and red for the blood shed in the struggle for independence with the 30 leaves in the wreath corresponding to the thirty years spent in the struggle. The flag has proportions of 1:2.
