The Color Changin' Click, is a local hip hop group formed in 2001 by Chamillionaire and Paul Wall. The group disbanded in 2005.Chamillionaire and Paul were part of a group prior to Color Changing Click called The Sleepwalkers. It's unclear if there were 3 or 4 members of the group, but PKT (short for Pimp Killa Thug) was definitely part of the group. Not much more is known about the group other than they used to open up for Swishahouse members prior to being in Swishahouse themselves.
