The fifth color of the Olympic rings is red; the complete set is blue, yellow, black, green and red.
French educator and Olympic movement founder Pierre de Coubertin created the rings in 1913. The five interlocking rings symbolise the union of the world’s inhabited continents and the meeting of athletes at the Games. The coloured rings, displayed on a white background, became the Olympic flag’s central design.
The flag was adopted in 1914, but the Olympic symbol first appeared at an Olympic Games when it was flown at Antwerp in 1920. The colours were chosen because, together with white, they could be found in the flags of every nation competing at the time.
A frequent misconception assigns one ring and one colour to a specific continent. That chart circulated historically, but it is not the official meaning: no individual ring officially represents Europe, Asia, Africa, Oceania or the Americas. Red is simply one of the five official ring colours, not a special “final” continent colour.
