The Olympic logo was conceived and designed by Mr. Pierre De Coubertin in 19 13, and was determined by the Olympic Charter. It is also known as the Olympic five-ring symbol and the most widely recognized Olympic symbol in the world. The five rings are composed of five Olympic rings in five colors: blue, yellow, black, green and red. The rings are nested from left to right, with blue, black and red rings above and yellow and green rings below. The overall shape is a regular trapezoid with a small bottom.
