The five interlocking rings of the Olympic Flag represent the five parts of the world embracing "Olympism" and competing against each other: Africa, The Americas, Asia, Europe and Oceania. The interlacing of the rings represents the unity and coming together of athletes from all parts of the world. The six colours of blue, dark yellow, black, green, red and white—the field on which the rings are set—"reproduce the colours of every country", and at least one is found on every national flag.
