Color Iz also peaked at number nine on Billboard's World Albums chart while "La Vie en Rose" peaked at number six on the World Digital Songs chart, making Iz*One only the eighth Korean girl group to have their debut release appear on both the World Albums and World Digital Songs charts.

Background and release
Iz*One was formed through the reality show Produce 48, the third season of Mnet's Produce 101 series of competition shows, in collaboration with Yasushi Akimoto's AKB48 Group, which aimed to create a "global" girl group primarily active in both South Korea and Japan. With the show wrapping up in August 2018, the group's label, Off the Record, announced that Iz*One will make their official debut later that year in October. Iz*One immediately started preparations for their debut after the show's finale and the members were put on a tight schedule as they recorded their debut album and filmed for various shows and their title track's music video, making it difficult for member Chaewon who also had to prepare for the College Scholastic Ability Test in South Korea.

The debut EP, titled Color*Iz, was announced two weeks prior to its release. Iz*One completed filming the music video for the album's lead single, "La Vie en Rose" on October 18, 2018.

Color*Iz was released October 29, 2018, along with the lead single's music video, through various music platforms, including Melon, Apple Music and Spotify. On November 4, 2018, Iz*One released a choreography video of "La Vie en Rose" on YouTube

Composition
The lead single "La Vie en Rose" is described by Billboard as a vibrant, groovy electropop track that blends a wide range of elements like ambient synths, stomping beats, tinny snare and echoing strings. The album also contains Iz*One's versions of "We Together", "You're in Love, Right?" and "As We Dream" which were featured on and originally performed by the contestants of Produce 48.

Promotion
Iz*One held a debut showcase concert, entitled "COLOR*IZ Show-Con", on October 29, 2018 at the Olympic Hall in Seoul, South Korea. The tickets to the showcase were sold-out within a minute of being on sale. The showcase was broadcast live on YouTube and Facebook. The group filmed for the South Korean variety show Idol Room on October 17, and the episode was aired on October 30 on JTBC. They also appeared on the October 31 episode of Weekly Idol.

The group made their debut stage on November 1, performing "O' My!" and "La Vie en Rose" on Mnet's M Countdown, followed by KBS' Music Bank and MBC's Show! Music Core. The group earned their first music show win on November 8, 2018 on M! Countdown, making them the fastest female group to win on a music show since debuting with a record of 10 days.

Music video
The official music video for "La Vie en Rose" is inspired by the color red, as the title is French for "The Life in Pink", with the twelve members seen singing and dancing in red-and-leather outfits. It was choreographed entirely by Chae Da-som, with the exception of the pre-chorus which was modified by member Kwon Eun-bi. It achieved more than 4.5million views in the first 24 hours of its release on YouTube, surpassing the previous record held by Stray Kids for most views of a K-pop group's debut music video within 24 hours. Four days later, the music video exceeded 10million views on YouTube.

Reception
Tamar Herman of Billboard opined that the lead single is "Captivating from the get-go" and that the group served up an introductory track that is "all at once powerful and delicate". She further added that "Rather than coming off as contradictory, the duality featured in Iz*One's debut song and video hints to the act's potential amid one of the most experimental pop music scenes in the world and highlights why these 12 were handpicked from among the nearly 100 women who competed for a spot in the group on this year's Produce 48".
