In preparation for an Active Shooter Course we put on, I once went to the food court of a popular local shopping mall, got a drink, and just sat at a table and observed. I had a notebook, and kept tabs of the outer garment colors worn by everyone that came and went in the course of an hour or so. Black, brown, blue, gray, and green in various shades were by far the most heavily represented colors. No one wore an outer garment that was an ugly orange/red color. That color front sight will, however, show up very well against any of the colors listed. A policeman would call this “a clue”.
