Choreographer: CORTIS, REMY, MUN HYUN & KIM JAEMAN
Released April 20, 2026 as the lead single for CORTIS's second EP GREENGREEN, REDRED debuted at #1 on Korea's Circle Chart and stayed there. The group collected five consecutive music show trophies: wins on Mnet M Countdown (April 30, May 7, and May 14), MBC Show! Champion (May 13), and their first terrestrial #1 at KBS2 Music Bank on May 15. Internationally the single reached #2 in Taiwan, #3 in Vietnam, #6 in Singapore, and spent three consecutive weeks on the Spotify Global Top 100. REDRED launched from a substantial base: the group's debut EP Color Outside the Lines had already set the record for highest sales of any K-pop debut album at 2.06 million Circle Chart copies, and GREENGREEN pre-orders crossed 2.02 million before the single even dropped.
Cultural Note
All five CORTIS members — Martin, James, Juhoon, Seonghyeon, Keonho — are credited as co-choreographers on REDRED, alongside collaborators REMY, MUN HYUN, and KIM JAEMAN. The movement vocabulary draws on 1990s aerobics, shuffle dance, and Tecktonik, then collapses into a single repeatable challenge move: the palrang-gwi (팔랑귀), Korean slang for someone whose opinion flips at anything they hear — 'flappy ears.' To execute it, shake both hands near your ears, then cross your arms into an X, literalising the song's traffic-light metaphor: red for playing it safe and caring too much about others' opinions, green for breaking through. The members co-directed the music video themselves in Seoul street scenes and vintage shops, consistent with the self-directed creative ownership they've maintained since their debut.
The palrang-gwi move requires visible hands positioned near the head — photos where your hands are raised near your face will produce the most readable version of the ear-shake sequence
The arm X-cross is a full-torso gesture; front-facing, torso-length photos capture it more cleanly than tight head shots
The choreography includes fast formation shifts and directional changes; a neutral or slightly open stance in the source photo gives the AI flexibility to animate the transitions
REDRED runs at 121 BPM — a moderate hip-hop tempo that allows sharp arm pops and held positions to register clearly between the faster movement bursts
