Colors (stylized colors) is the fourth major-label Japanese studio album (sixth overall) by South Korean pop rock band CNBLUE. It was released on September 30, 2015, under Warner Music Japan. After releasing the first single "White", the band decided to continue with the theme of color to showcase musical variety through the album. "Supernova" was released as the album's promotional single in September.

Colors was released in four editions: Regular Edition, Limited Editions A and B, and a fan club-only Boice Limited Edition. It went on to debut at number one on the weekly Oricon Albums Chart, the first time in over three years since CNBLUE topped the chart. The band embarked on the CNBLUE 2015 Arena Tour: Be a Supernova from November to December in Nagano, Tokyo, Aichi, Fukui, and Osaka.

Colors was announced as CNBLUE's fourth studio album on July 24, 2015, with a release date of September 30. The title is meant to indicate the array of "colorful music" included on the album. After releasing "White", the band decided to continue the theme to showcase more of its musical color. Vocalist Jung Yong-hwa compared the album's varying musical styles to a rainbow. In discussion of the album, guitarist Lee Jong-hyun described that there is no significant difference between CNBLUE's previous album Wave. He explained that, "I don't usually try to change... with time, the piece will naturally change." He noted that the band "played around with sounds", pointing out development in that area; musically, "it's still simple". He felt that the key point of the album was to appeal to a broad audience and be easy to listen to. In midst of his solo activities, Jung Yong-hwa took opportunities to record phrases and sounds before forming them into new songs.
