Profile
CORTIS (코르티스), short for Colour Outside The Lines, is a five-member South Korean boy group under BIGHIT MUSIC, represented in the U.S. by Republic Records. Originally known as BIGHITNBG (BIGHIT New Boy Group), the lineup consists of Martin, James, Juhoon, Seonghyeon, and Keonho. First introduced in April 2025, the group was described as a “next-generation creator crew” for their active participation in songwriting, choreography, and visual production, with members even contributing to projects for senior HYBE artists before debut. On August 11, 2025, they dropped their pre-debut single “GO!”, blending Y2K-inspired sounds with trap and synths. Just a week later, on August 18, 2025, they officially debuted with the single “What You Want,” a genre-bending track fusing psychedelic rock and hip-hop. Their first EP, Color Outside the Lines, was released on September 8, 2025, showcasing their experimental and boundary-pushing identity as artists.
