ColourTheory (previously known as donkeyo4) was one of the most respected, renown and reforming leaders of the famous Roblox Assault Team. He has led RAT a total of two times, succeeding ThePhantonHourGlass's first reign, and preceeding his rival, cjsaurusrex. ColourTheory has been a prime inventor of the current RAT today, and it would be a dump without him.
After leaving and handing the group to Cj, he left to college and mysteriously returned with a rebellion against RAT -- the New Frostarian Union, co-hosted by Tenal and former colleagues of Donkey. However, over time, it became its own clan and family, contributed to by even RAT's own blobmista4.
