Indigo (born Alyssa Ashley Nichols, 25 June 1984, Los Angeles) is an American actress, DJ and entrepreneur. She is best known for her roles as Rona, one of the vampire slayer potentials, in the final season of the TV series Buffy, the Vampire Slayer, and Vaneeta on the Showtime series Weeds, in which she was nominated for the 13th Annual Screen Actors Guild Awards, for Outstanding Ensemble in a Comedy Series.

Indigo is the third album by British pop/ jazz/ soul/ dance band Matt Bianco, released in July 1988.

This was Warner Brother's attempt to launch Matt Bianco in the U.S., hence the hiring of Emilio Estefan ( Gloria Estefan's husband) as producer. He contributed three of the tracks on the album, including the first single ' Don't blame it on that girl'. By reaching Number 23 in the UK albums chart, it became the highest-charting long playing work for the group, and it also included their highest-charting single ever, the double A-side "Don't Blame It on That Girl" / "Wap-Bam-Boogie", Number 11 in the UK singles chart. The album follows the path started with the previous LP, the eponymous Matt Bianco of 1986, achieving even more success. Besides the big success of the first double a-side single, especially the dance-oriented "Wap-Bam-Boogie" ("Don't Blame It on That Girl", though pushed high in the charts by the other track, actually had a limited impact), the long playing work was promoted by three more singles: "Good Times", "Nervous", and "Say It's Not Too Late", none of which had any commercial success, stalling in the lower parts of the charts - the third single did not even enter the UK Top 75, and it would be in fact re-included as a B side on " What a Fool Believes", the second single from the fourth studio album by the band, Samba in Your Casa of 1991.

The success of "Wap-Bam-Boogie" was instead so huge as to push the group not only to release a number of remix versions of the hit, either at the time and in the next years, but it even prompted them towards a dance revolution in their style which, though disappointing early fans, would gain them new ones; however, it must be noticed that, maybe for a matter of balance, their next studio album, the mentioned Samba in Your Casa, would feature a much more Latin pop-oriented sound than their previous long-playing works, though not abandoning dancey rhythms. A final mention should go to the 2 bonus tracks only contained in the compact disc edition: two remixes of two of the five singles taken from the album: the «12" Mix» of "Dont' Blame It on That Girl", and the «Miami Mix» of "Good Times".

Indigo is a debut album by Slovenian vocalist Maja Keuc. There's 11 songs on the album that are a mix of pop, jazz, soul and blues rhythms. Half of the songs are in English and there is a remixed version of Eurovision song No One.

Indigo is the fourth studio album by American rock band Never Shout Never. It was released on November 13, 2012 by Loveway Records. The album features the band recording as a whole for the second time; the first being in Time Travel. A bonus track was made available through some media outlets and also on the limited edition cassette tape. The album debuted at number 194 on the Billboard 200.
