They debuted on August 18, 2025, with the digital single [“What You Want"](https://kpopping.com/musicalbum/2025-What-You-Want) followed by their first EP, ["Color Outside the Lines"](https://kpopping.com/musicalbum/2025-COLOR-OUTSIDE-THE-LINES). The group’s name is derived from the phrase “Color Outside the Lines,” reflecting their concept of creative freedom and nonconformity. Cortis has been promoted as a self-producing “creator crew,” with members participating in songwriting, choreography, and visual direction. Blending pop, hip-hop, and experimental elements, the group gained early attention for their performance skills, self-produced content, and strong rookie-year sales, establishing them as one of Big Hit Music’s newer generation acts.
