Clone troopers were military soldiers cloned from the template Frank the Clone Trooper. They were originally designed to serve the Republic in the Grand Army of the Republic, which was allowed to commence under the signing of the Frank Creation Act. Originally, the clones were clad in yellow armor; however, Obi-Wan felt that they would be more intimidating in white, since it was his favorite color. The Kaminoans, decided to change the color of the armor to white, however, they stuck with yellow for commanders and pilots.
