- 2011Around So Girls and Sweet Dream the grown-up sound and the lingering vocals became easier to hear.

- 2014RB BLAXX, with Jaekyung, Woori, Seungah and Hyunyoung, opened a more grown-up lane on the side.

KPOP DISCOVER's Rainbow note
Rainbow is the seven-piece girl group that DSP Media debuted on November 14, 2009. Coming from the company that produced KARA, and named for the seven colours, they built on dance pop that pushed the individuality of all seven. The fandom is called Rain-nous, the run crossed Korea and Japan until 2016, and in 2019 a member-led reunion came together for the tenth anniversary.
The entrances to hold on to are A, To Me and Sweet Dream. A is the signature work that stamps the presence of the seven in an instant with its hook and bursting energy, and a Japanese version was made as well. To Me steps into a more polished sound, and Sweet Dream shows a slightly grown-up face with a lingering finish. Beyond bright dance pop, the moments where the vocals gain depth can be heard from early on.
Korean work stacked up through Sunshine, Black Swan and Whoo, and in 2014 the unit RB BLAXX with Jaekyung, Woori, Seungah and Hyunyoung opened a grown-up lane on the side. In 2016, with Whoo from the album Prism as the last release, the contract expired and group activity ended. On November 14, 2019, for the tenth anniversary of the debut, the members led the release of Over the Rainbow and showed that the bond between the seven still holds. A, then Sweet Dream, then Over the Rainbow runs through the signature work, the grown-up finish and the anniversary reunion.
Editors' take A / Sweet Dream / Over the Rainbow — a DSP Media seven-piece from bright dance pop to the tenth anniversary reunion in three songs.
Trivia worth knowing
Name
The name casts the seven members as seven colours, and learning who carries which shade makes the line-up easier to hold.
Entry point
A is the largest entry point of all, and the Korean video, the Japanese video and the official stages together show the second-generation character.
Japan activity
Treating A, Mach and Gonna Gonna GO! as releases for Japan clarifies how DSP Media moved into that market after KARA.
Unit
Cha Cha by RB BLAXX is a side project that shows a more adult lane away from the main group.
Later years
Black Swan and Whoo mark the move from the bright beginning to a more mature later face.
Regrouping
Aurora is the special song for the 10th anniversary, proof that the seven stayed connected after activity ended.

Japan activity score
KPOP DISCOVER original metric
No. 116/ 241 groups
No. 116 of 241 groups with recorded activity in Japan (top 48%)
- 3Japanese releases
- 6Japan-related tracks
- 0Members from Japan
- 0Official Japanese accounts
The denominator is the 241 groups, out of 564 covered by KPOP DISCOVER, whose raw score reaches at least one point. The score adds 10 points per Japanese-market release, 3 per Japan-related track, 12 per member from Japan, and 8 per official Japanese account. Japanese-market releases carry the most weight because they are the most direct evidence of activity; related tracks add track-level detail; members from Japan stand for Japanese-language communication and continuity; official accounts stand for a permanent point of contact. The weights are an editorial judgement, not a statistical optimisation, and the ranking tracks release volume in Japan closely.
