whats the name of the song/group...?

that in the video the singer (a girl) has a blue jumpsuit, and people is dancing like in a flashmob; all the dancers are wearing like the rainbow colors tshirts. They start dancing in spiral and rise the singer, this is all i remember :( i saw the vid just once in VeVo channel in youtube and i can't find it now!

Also i believe the lyrics say something about blue skittles or whatever skittle color xD something like that! The music is kind of indie, alternative or so..

Help!! Thanks !
