"Irohanihoheto" (いろはにほへと^?), also known by its French title "Les Couleurs Chantent" ("The Colors Sing"), is a song by Japanese musician Ringo Sheena. It was initially released digitally on April 30, 2013, and on May 27 released as one of the A-sides of her 14th single, along with the song "Kodoku no Akatsuki". The release date was the 15th anniversary of the release of Sheena's debut single "Kōfukuron" in 1998. The song was used as the theme song for the drama Kamo, Kyōto e Iku.: Shinise Ryokan no Okami Nikki.

In early 2012, Sheena's band Tokyo Jihen disbanded, and released a string of releases, including the extended play Color Bars, the live compilation album Tokyo Collection, the B-side collection Shin'ya Waku, and performed their farewell tour, Bon Voyage. On May 16, 2012, Sheena released her first post-Tokyo Jihen solo work, the digital single "Jiyū e Michizure." This song acted as the theme song for the TBS drama Ataru, starring Masahiro Nakai.

It was later revealed that Sheena was heavily pregnant with her second child during the single's release. As she did not feel it was appropriate to link single promotions with the birth of a child, she waited until her Tōtaikai concerts in November to reveal this.

Sheena worked together with producer and gutiarist Yukio Nagoshi on the song, as well as "Kodoku no Akatsuki". Sheena had previously worked with Nagoshi during her Ringo Expo concerts in 2008, and on the songs "Zero Chiten Kara," "Togatta Teguchi" and "Yokyō" on her solo album Sanmon Gossip (2009). Her previous Tokyo Jihen bandmate Ichiyo Izawa played the harpsichord on "Irohanihoheto." Bassist Hitoshi Watanabe had previously worked with Sheena as a member of Bōtoku Vitamin, one of the bands who performed on her album Utaite Myōri: Sono Ichi (2002). Drummer Noriyasu Kawamura previously worked with Sheena on her debut album Muzai Moratorium (1999).
