Olympic Flag

I wonder who the creator of the Olympic flag was? Well Pierre De Coubertin was the original  person to discover the design of the Olympic Rings. It comes in six different colours , blue, black and red for the top 3, yellow and green for the bottom 2 and they appear on a white base layer. While some people believe that he had chosen these main colours, to represent 5 different continents, on the other hand others appear to believe that these colours come together to represent all nations race. I have read that the colours represent all the athlete that compete around the world in the olympic games
