The flag of the Republic of South Africa was adopted on 27 April 1994, at the beginning of the 1994 general election, to replace the flag that had been used since 1928. The new national flag, designed by State Herald Frederick Brownell, was chosen to represent the new democracy.
The flag 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.
Three of the colours – black, green and yellow – are found in the banner of the African National Congress. The other three – red, white and blue – are displayed on the old Transvaal vierkleur (which also includes green), the Dutch tricolour and the modern flag of the United Kingdom.
