<P> I was wearing them on the street . What's wrong with wearing them on the air? I wore' em on airplanes . It was the era of the miniskirt . Everybody wore miniskirts . </P> <P> On certain occasions, the characters wear dress uniforms (TOS: first shown in "Court - Martial" and later used in "Space Seed," "Journey to Babel," and "The Savage Curtain") that are made of a shinier fabric, presumably a polyester satin, and are decorated with gold piping and colored badges that vary depending on rank . Montgomery Scott's dress uniform, especially as seen in "The Savage Curtain," includes a Scottish tartan . Specifically, it is the tartan of the Clan Scott, one of Scotland's oldest clans . Jumpsuits in the same colors with black undershirts were also worn, mostly by background characters . </P> <P> 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 . 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 . 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". </P> <P> Based on the success and increasing popularity of Star Trek in syndication, an animated version of the series was produced from 1973 to 1974 . The uniforms depicted in this series matched the general parameters and appearance of those used in the live action series . The perception by fans of the command uniforms being yellow / gold instead of green, thanks to set lighting and other factors, resulted in the producers committing to a definitive gold - color for animation purposes . The command dress uniforms remained green to match the perceived colors represented by the live action series . However, the uniform pants were colored gray to match the actual fabric used in the live action series as opposed to the black they had appeared to be when filmed . </P>
