The Wonder Girls is now officially South Korea's official representative for the MTV Iggy and Chevy "Cover the World Global Music Challenge". And last night, they dropped the official video via MTV Iggy's Plug Into K-Indie section. The video will also be up on the official Cover The World website beginning October 22nd, where fans can vote for their favorite cover.

In the video, the girls are seen singing acapella to the song "True Colors" and wearing very simple and natural-looking makeup -- really showing their real personas, their true colors.

Other artist finalists for the challenge include Gyptian from Jamaica, All Time Low from the United States and Angus Stone from Australia. The contest lets fans vote for their favorite artist for a chance to win a Chevy Spark as well as a chance to see the winning artist perform live.
