The Off Colors are a group of unaligned Gems who present abnormal physique, behavior, or abilities and have been deemed "defective" and "off-color" by Homeworld's strict standards and Caste System.
They lived reclusively in an abandoned Homeworld Kindergarten for eons before the site was compromised with the arrival of Steven and Lars.
The Off Colors, now with Lars serving as their leader, escaped Homeworld and went on many adventures and committed crimes against Homeworld's regime. Eventually, they stole a ship from Emerald and defeated her in a space battle with the help of Stevonnie, before heading to Earth on a lengthy interstellar trip.
In "Change Your Mind", Lars and the Off Colors finally arrived on Earth to discover Steven had made peace with the Great Diamond Authority, allowing the Off Colors to live without fear. After the events of "Little Graduation", however, most of the Off Colors graduated from Little Homeschool and the team opted to return to space for further adventures.
