The K-pop group CORTIS has achieved a major milestone with its debut album "COLOR OUTSIDE THE LINES" exceeding 2 million cumulative sales, according to Circle Chart data. This marks only the second time a K-pop group has reached double million seller status with a debut release. The group is preparing for an April comeback with a title track on April 20 and a full album on May 4.
CORTIS, consisting of members Martin, James, Joo Hoon, Sung Hyun, and Geonho, debuted with "COLOR OUTSIDE THE LINES" in September 2025. The album reached 500,000 sales by September 25, 1 million by November 25, and surpassed 2 million copies as of the Circle Chart weekly album chart released on March 5, 2026, covering the period from February 22 to 28. Various editions, including Singing Bowl, LP (Vinyl), CORTIS Ball, regular, and Weverse versions, have maintained strong demand, often selling out upon restock.
The album's enduring popularity is evident on international charts. As of the Billboard chart released on March 7, 2026, "COLOR OUTSIDE THE LINES" has charted for 25 consecutive weeks on the World Album list. It climbed to 24th place on Top Album Sales, up nine positions from the previous week and marking the second consecutive week of gains. This follows CORTIS's Billboard 200 debut and builds on performances such as appearing at a National Basketball Association weekly event as the first K-pop act and contributing the song "Mement Me" to a Sony Pictures Animation project.
Fan engagement has also driven success, with the group's official YouTube channel boasting a top video view count of nearly 8 million and 37 clips exceeding 1 million views, excluding shorts. CORTIS is teasing its upcoming comeback, including a collaboration revealing lyrics for the new song "YOUNGCREATORCREW" through the "Hankom Bazaar" typing practice service. The title track is slated for release on April 20, 2026, with the full album following on May 4, aiming to expand global reach.
