The flag of Rwanda was adopted on October 25, 2001.
The flag has four colors: 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 difference between the two yellows is barely noticeable.
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 flag was designed by Alphonse Kirimobenecyo.
