The flag of the Republic of South Africa has horizontal bands of red (on the top) and blue (on the bottom), of equal width, separated by a central green band which splits into a horizontal "Y" shape, the arms of which end at the corners of the hoist side (and follow the flag's diagonals). The Y embraces a black isosceles triangle from which the arms are separated by narrow yellow bands; the red and blue bands are separated from the green band and its arms by narrow white stripes. The stripes at the fly end are in the 5:1:3:1:5 ratio.
