The primary colors of the Olympic rings are blue, yellow, black, green, and red, with white as the background. These colors were chosen because at least one of these colors appears in the flags of all participating nations at the time the Olympic symbol was created in 1913. The rings are interlaced to symbolize unity and cooperation among the countries competing in the Games. Each color represents diversity and inclusivity, reinforcing the Olympic spirit of bringing people from different nations together through sports, promoting friendship, and celebrating athletic excellence around the globe.
