According to Rolling Stone, the group's name originates from the phrase "Color outside the lines," reflecting a spirit of boundless creativity. This is also the title of their debut EP, a music release with fewer songs than an album. Additionally, the naming was inspired by cortisol, a hormone associated with controlling energy, actions, and emotions. *Photo: Instagram/ Cortis*

Before releasing their first single, 'What You Want,' the band unveiled the music video for 'GO!,' which all members produced.
