I would use the pink color as a tie in to people with money wanting to be on the high orbit / space list. (Space X, Virgin Galactic, etc) They just barely know the basic and paid to be here. And its any easy color to keep an eye on / avoid. (the tour group) As for black, sound more like internal security, (Thinking Babylon 5) as dressing close to a Blacktron figure would get you shot.
