Sekai wa Anata no Iro ni Naru (世界はあなたの色になる, The Color This World Will Takes Depends on You) is a digital single by B'z, released only in Japan on October 4, 2016 via the Japanse iTunes store and all other major online music retailers in the country. While B'z has had digital endeavors such as the 2012 globally-released English album and the 2007 International EP, this is their first Japanese digital exclusive single, although Koshi Inaba has used the format successfully for his solo projects beginning with "Nensho" in 2014.

The song was first unveiled at the end of February 2016 when premiered during a trailer to the twentieth film in the Detective Conan franchise, The Darkest Nightmare. The song would serve as the theme to the film and months later as the opening to the television series.

Track listing

The song was written to suit the twentieth Detective Conan film entitled The Darkest Nightmare, for which it served as the theme. B'z explained the darker and harder sound by stating, "This movie focuses a lot on the darker parts of Conan's story and thus we made the theme song with a different feeling."

All music and guitar by Tak Matsumoto. All lyrics and lead vocals by Koshi Inaba.
