By the Numbers
The credits get deeper rather than wider. Martin writes all six and produces three, Seonghyeon writes five, and Keonho, Juhoon and James are on five, five and three. Hiss Noise and Supreme Boi are on all six as writers and producers both. “RedRed” carries thirteen writers and “Acai” thirteen, which is where the label machinery shows, but the members are inside those lists rather than outside them.
GreenGreen is the second EP by Cortis, released on 4 May 2026 through BigHit Music. Six tracks run sixteen minutes across alternative rock, hip hop and EDM. Lead single 'RedRed' reached number one on South Korea's Circle Digital Chart, the group's biggest commercial success.
