Cyan (stylized CYAN) is the second extended play (EP) by South Korean singer and songwriter Kang Daniel. It was released on March 24, 2020 by Konnect Entertainment and distributed by Sony Music Korea. Cyan contains five tracks with "2U" serving as its lead single. "Touchin'" was pre-released in 2019 and included in the EP.

Background
On March 2, 2020, Kang posted on his Instagram account for the first time since his hiatus in December, updating that he completed recording music. Following that post, Konnect officially announced a return in March. On March 9, Konnect confirmed Kang would release his first mini album Cyan on March 24. Pre-orders began on March 11.

Kang described Cyan as the "first button" in the process of finding his true colors as part of his "color trilogy" project. For Cyan he aimed to project positive energy and put his dreams, passion, and challenges with the cyan color. He took part in the process of making the album from track selection and recording to choosing the release themes, working on the choreography, and being involved with music video production. In an interview with Grazia Korea, Kang was asked about the goal of this first installment. He responded that the album was released shortly after his break, so he wanted the songs to be enjoyable to listen to. Just hearing that his songs were good meant he achieved his goals. Cyan was about new songs, and the next album in the trilogy encompasses what he is good at in addition to showcasing new things.
