Star Wars Clone Troopers

Do the different colors mean anything?  I've seen some with red, some with blue, some with orange, etc...  Do the different colors represent the different divisions of the Republic army, or are the colors just completely random?

I believe it signifies rank.

Correct. Wiki claims

    * None - Trooper
    * Light green - Sergeant; command squads, made of 9 troops. Green is also the color designated to Jet troopers in the Battlefront series of video games.
    * Blue - Lieutenant; command platoons, made of 36 troops (4 squads) Blue is also the color designated to ARC troopers in the Battlefront series of video games.
    * Red - Captain; command companies, made of 144 troops (4 platoons). Red is also the color designated to Clone Sharpshooters in the Battlefront series of video games.
    * Yellow - Commander, tasked with leading regiments of clones (2,304 in total, 16 companies) into battle. Yellow is also the color designated to Clone pilots in the Battlefront series of video games. Clone commanders were grown with more capacity for independent thought than lower-ranking troops. It was from these ranks of original clone commanders that the ARC Commanders were born. Notable clone commanders included Cody, Bly, Gree, Bacara, Appo, Keller, Neyo, and Thire.

Interesting.  So the colors do indicate rank and represent different divisions.
