Rwanda

The flag of Rwanda was adopted on October 25, 2001. ... The flag has four colours: blue, green, and two forms of yellow (standard yellow for the middle band and what the Pantone system calls "sun yellow" for the sun). The blue band represents happiness and peace, the yellow band symbolizes economic development, and the green band symbolizes the hope of prosperity. The sun represents enlightenment. The new flag represents national unity, respect for work, heroism, and confidence in the future. It was adopted to avoid connotations to the 1994 genocide. The flag was designed by Alphonse Kirimobenecyo. [Flag of Rwanda. Wikipedia]
