Two equal width horizontal bands of red (top) and blue separated by a central green band that splits into a horizontal Y, the arms of which end at the corners of the hoist side; 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 flag colors do not have any official symbolism, but the Y stands for the "convergence of diverse elements within South African society, taking the road ahead in unity"; black, yellow, and green are found on the flag of the African National Congress, while red, white, and blue are the colors in the flags of the Netherlands and the UK, whose settlers ruled South Africa during the colonial era.
