How many colours are included on the national flag of South Africa?

The flag of South Africa was designed in March 1994 and adopted on 27 April 1994, at the beginning of South Africa's 1994 general election, to replace the flag that had been used since 1928.

There are six colours used in the flag. 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 or gold bands; the red and blue bands are separated from the green band and its arms by narrow white stripes.

Three of the flag's colours were taken from the flag of the South African Republic, itself derived from the flag of the Netherlands, as well as the Union Jack, while the remaining three colours were taken from the flag of the African National Congress.
