Two years later, in late 2006, three of the four members left the group. ATSUSHI became the producer while TAKA became the new leader, and three new members joined COLOR.
On June 30, 2009, they changed the group's name from COLOR to DEEP, and announced that they were not longer produced by ATSUSHI.
On December 31, 2018, member RYO left the group and retired from singing activities.
On July 22, 2019, a live event titled DEEP VOCALIST AUDITION ~FINAL STAGE~ was held at Akasaka BLITZ and the members revealed that DEEP will continue activities as a trio but they started a new entertainment project titled DEEP SQUAD, including the members and the three winners from the audition: Uhara Yuhi, Sugiyama Ryoji and Higa Suzuki.
Note: all releases are under the name DEEP except when mentioned.
