what do the color shirts in star trek mean
Star Trek uniforms Beginning with the first regular series episode "The Man Trap", the department colors were slightly altered from the pilot versions: command and helm personnel wear gold shirts; operations, engineering and security personnel wear red; and science and medical personnel wear blue, all with black collars and undershirts.[notes 1] The most commonly used Command Section shirts were actually olive-green in color, but they appeared to be a golden-yellow color called "tenne" both under the lights used on the set and in the post-development film stock. In later series, the gold color was canonized in dialog. However, some uniforms – the alternate shirts worn by Captain Kirk, and the Command Section dress uniforms – were made of a different material which, while the same color, showed up as olive-green even under the lights and when photographed.[5][6][notes 2] The green shirts (seen in TOS: "The Trouble with Tribbles", "Charlie X" and "The Immunity Syndrome") may have the rank stripes on the sleeves or on the collar (TOS: "The Enemy Within"), and always feature the Enterprise assignment patch near the waist as a belt fastener. The frequent death of red-uniformed security officers led to the coining of the popular term "redshirt".
