Chroma is the debut studio album by the American rock band Cartel. Formed in mid-2003, they self-released an EP the following year. Shortly afterwards founding guitarist Andy Lee left the band and was replaced by Nic Hudson. Following a performance at a music conference in Atlanta, the band signed to The Militia Group. With songs planned out, the band went to record with producers Zack Odom and Kenneth Mount. Recording took place at Treesound Studios in Atlanta in May and June 2005. Chroma released through The Militia Group in September 2005. The album sold 3,000 copies in its first week and charted at number 140 on the Billboard 200 chart. Chroma is the only full-length Cartel album to feature bassist Ryan Roberts, who departed the band in 2006.
