The five multicolored Olympic rings are linked because they symbolize the unity of athletes from all parts of the world who participate and compete against one another at the Olympic Games, according to Olympics Go for the Gold. These rings represent the union of the five continents. Moreover, they are interlinked to show that all nations are free to participate in the games.
The rings represent the continents of North and South America, Europe, Asia, Africa and Australia. However, according to the Olympic Movement, each of the colors of the rings does not correspond to a particular continent. When Pierre de Coubertin designed the Olympic rings in 1913, the five colors were merged with a white background, and they represented all of the nations at the time. Olympics Go for the Gold explains that Pierre de Coubertin wanted to make sure that the Olympic flag would be universally accepted by all of the participating countries, and he also wanted the flag to be a part of the new Olympic tradition.
The Olympic symbol is composed of five interlaced rings with equal dimensions. From left to right, the five colors are blue, yellow, black, green and red. The flag is used in both the winter and summer Olympic events.
