Background
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.

Music structure
"Supernova" is a rock song accompanied by guitar riffs and a synthesizer with an "analog feeling". Jung Yong-hwa wrote the song with Star Wars, and the general idea of the silence in outer space, in his mind. He elaborated, stating: "When I watch films that portray the universe, it opens up a space in there with only me inside... I wanted to express that space of quiet tranquility as the universe. That was the thought." "White" is an electronic rock song that also features a synthesizer. "Irony" is a song that pertains to a couple that no longer love each other, but reject the idea of a breakup as a result of the empathy felt for one another. A jazz pop song, "Hold My Hands" was previously recorded in Korean for CNBLUE's studio album 2gether. Writing the lyrics first, Jung Yong-hwa set out to "portray this speechless feeling of being moved at the heart" in a subtle manner. "Daisy" was co-composed by bassist Lee Jung-shin, his first contribution in that area since joining the band. He composed the song using a guitar, which he played it for Jung Yong-hwa while seeking guidance. After implementing suggested changes, Lee Jung-shin wrote the lyrics.
