Special forces are hard to say, because in fact, domestic special forces have never really appeared in film and television works, and even some military documentary columns of TV stations have never been to the barracks of real special forces. Special police and special forces are not the same organization at all, they all belong to the police force. In general, they don't need camouflage at all, but they need to be recognized by the masses and criminals at a glance, so they usually use the most conspicuous black as the main color. In this case, all kinds of equipment on them only need to be considered in actual combat, and there is no need to have too many requirements for color matching.
