Rainbow is set to make their long-awaited comeback on February 13th with their first studio album, "Rainbow Syndrome". The album is supposed to have a bright and healthy image, with the concept of the photos as 'Sweet Party Girl'. Most likely it is related to Valentine's day. DSP has stated that there will be a Part 2 to showcase Rainbow's different styles and changing music.
The comeback schedule for the next few days is as follows:
02/06 Jae Kyung, Seung A, Yoon Hye & Hyun Young photos
02/07 Woo Ri, No Eul, Ji Sook & Group Photos, Video and Track List revealed
02/08 Rainbow set greeting special video
Hyun Young and Yoonhye
Jaekyung and SeungA

It isn't clear what Part 2 really means, as in another studio album, a mini album, or a repackage. Mostly likely though it will show off a different image than this.
