The Gramercy Riffs take their name from Gramercy Park, a private park in an affluent Manhattan neighborhood. This is the kind of place you'd expect gang royalty like Cyrus to live.
The Riffs “colors” are orange robes, but in the final scene they wear plain black jeans and t-shirts because they are on the Warriors turf, and wearing colors on someone else’s turf without permission or parlay is disrespectful and considered an act of war.
The tagline that the gangs "outnumber the cops 5 to 1" and "could run New York city" was disturbing enough to the public that the film posters had to be recalled and the trailers altered to remove this line. Another factor was that it could inspire real gangs to start riots.
