TMC, also recognized as TooManyColors, is an upcoming male duo slated to debut in 2023 under MyDoll Entertainment, the same label that brought us Pink Fantasy.

On November 29, 2022, MyDoll Entertainment unveiled their newest act by launching social media accounts for TMC, introducing its members: former Apeace member Wonsik and Seunghyuk.

Marking their entry into the music world, the duo dropped a pre-debut digital single titled "Color" on June 20, 2023. Not long after, on July 2, they teased fans with a photo hinting at the Japanese version of "Color", set to release on August 2. Their momentum didn't stop there. On August 10, they followed up with a second pre-debut single aptly titled "Too Many Color".

But it's not just about the music. On September 6, 2023, TMC announced their official fandom name: "TOUR":

"TMC+OUR means that TMC members and fans will become one and travel together in the future.

In the future, we will do our best to make many good memories together with the TOUR.

Thank you."
