According to most accounts, the rings were adopted by Baron Pierre de Coubertin (founder of the modern Olympic Movement) in 1913 after he saw a similar design on an artifact from ancient Greece.? The five rings represent the five major regions of the world: Africa, the Americas, Asia, Europe, and Oceania. Every national flag in the world includes at least one of the five colors, which are (from left to right) blue, yellow, black, green, and red.? It is important to emphasize that Pierre de Coubertin never said nor wrote that the colors of the rings were linked with the different continents ....... Hope that helped .-.
The olympic rings were originally designed in 1912 by Baron Pierre de Coubertin, the founder of the modern Olympic Games. According to de Coubertin, the ring colours with the white background stand for those colors that appeared on all the national flags that competed in the Olympic games at that time.
From the official Olympic website: The five rings that make up the Olympic symbol
represent the union of the five continents and the meeting of athletes from all over the world
during the Games. They symbolise the universality of the Olympic Movement.
