Personally, I don't care for either bright colors or the camo/tactical look. Most of my gear tends toward low key, low observable earth tone shades of green, tan or brown, as can be seen in my photo.

When backpacking, I really don't want to see others or be seen myself. In the wilderness, I consider bright neon colors a form of visual pollution. The safety aspect some would raise may be over-stated, except maybe for young kid's clothing or in active hunting areas. I carry a blaze orange bandanna in my pocket, and consider it sufficient for my emergency conspicuity needs.

However, I do like reflective guy lines around camp, since I dislike tripping and crashing into my tarp setup. Also, a tiny low power LED strobe left flashing temporarily in camp usually makes returning from night time forays a cinch, and is often more effective for that purpose than a lumen cannon in one's pocket. I also use orange colored paracord on small items as a lanyard or wrist cord. I even have GITD skull beads on some flaslight lanyards.
