It used to be that outwear, especially hard shells, rain gear, and windshirts was available in bright colors; not any more. You really have to search to find something other than black, navy blue, or charcoal - especially for men. International orange is sometimes seen, but yellow (O2 Rainshield notwithstanding)and red have all but gone.
Many of us LIKE to be visible on the trail. For the rest, there is a plethora of blend-into-the-background, dull or cameo colors.
