Well it sounds like ASB but if you handle it right it is possible. I mean we have Vice Lords, Reformed Vice Lords, Gorillia familys, Aryans, Crips (one point had canes), and a lot more gangs.
So make Star Trek a clothing option by Tookie Williams. He wore blue to tell his men apart, well for the hell of it Star Trek is on and he decides he will wear yellow cause he is the Captain, and his friend Raymond Lee Washington wears blue as his officer, and the rest wear red. Black pants, black combat boots, and a colored shirt is all they need. The choice was between three others "Cribs", the Black Overlords, and the Assassins. Wanting to stand out and make an impression, after all the gang was formed to protect their homes they decided to be the Starboys.
Wearing bright uniforms, and beating down any in their way they became a very famous force with in Los Angeles. Other gangs decided to join, and it quickly grew into a major criminal organization. By this time the Starboys became the Treks. Major groups were the Compton Treks, Eastside Treks, and the Red Treks.
Alongside this gang was a smaller group made for simple protection from the growing Trek gangs. The Pirus Street Gang was doing its best to deal inside of Los Angeles against the growing Trek influence. Deciding to ally with other gangs dotted about LA. The color choices were to be white and black as the Treks had vibrant colors. As a joke some starting refering to themselves as Stormtroopers after the film Star Wars which came ot two years earlier in 1977. As the Treks and the Stormtroopers clashed over areas of LA the culture of the gangs started to expand.
Crack, guns, and violence turned the inner city into a war between the Treks, the largest being the Redshirt Treks, and the Doc Treks, and the more heavily armed Stormtroopers, or Warz depending on the gang. By the 1980's the gang culture was firmly in place. If one wore colors and was black they were Treks, if white and black then Stormtroopers. Needless to say aspects of cinema suffered. A planned sequel in 1980 for Star Wars was cancelled due to the overall connection to violence. As one producer said, "I got this Starwars script and thought it was a version of Godfather for the inner city."
Just as Star Trek was seeming popular on the big screen a sequel in 1982 was canceled as the studio had another film called "Trekkies" in the works about a drug dealer in South Central, and feared the public would not react well.
