What do the Olympic rings mean?

The colors of the five interlocking rings represent the five participating continents: Australia, Africa, America, Asia, and Europe. The colors are always arranged with blue, black, and red across the top from left to right, and yellow and green along the bottom. Some suggest that each color stands for a particular continent, but this has not been confirmed. The rings first appeared on the Olympic flag in 1913, designed by Baron Pierre de Coubertin, the founder of the modern Olympics.
