Why are there five rings in Olympic logo? And what does they symbolize?<|im_end|>
<|im_start|>assistant
The five interlocking rings of the Olympic logo represent the five inhabited continents of the world, namely Africa, the Americas, Asia, Europe, and Oceania. The colors of the rings—blue, yellow, black, green and red—were chosen because at least one of the colors appears on the flag of every nation in the world. The rings are linked together to symbolize the unity and friendship among nations that are fostered by the Olympic Movement.<|im_end|>

According to the International Olympic Committee's official website, "when Pierre de Coubertin created the Rings in 1913, the five colours combined with the white background represented the colours of the flags of all nations at that time, without exception," In other words, the colors do not correspond to particular continents. 
The rings are each equally dimensioned, which could be interpreted as equality between all.<|im_end|>
