Kaleidoscope is a song written by Svante Halldin, Kerli, and Jakob Hazell for Kerli's second studio album Utopia, which later became an extended play. Benny Benassi later made a remix that was published officially as a Benassi song featuring Kerli on Ultra Music's YouTube channel on July 25, 2014.
The song leaked in December 2012, along with a lot of songs, including Last Breath, Chemical, Love Me or Leave Me and Here and Now. In February 2013, after the massive leakage that included the whole album Utopia —only excluding I Was Made for Loving You, which remains unleaked as of late 2018—, Kaleidoscope was scrapped from the album along with Speed Limit, Supergirl and Last Breath, while the previously released singles Army of Love and Zero Gravity were also removed from the final track listing.
The song runs at a moderately fast tempo of 128 beats per minute, and is set at a 4/4 time signature. Musically, Kaleidoscope incorporates electronic beats through the verses and the hook, while the chorus is sung over an atmospheric, piano structure.
