I have a mixture of civilian colours and OD for the big stuff (clothing and pack). I like OD because it blends in the background. Having the same colours as the surrounding makes you feel more a home. The more moderne and lighter weight equipment seams to be all civilian so i'm shifting to civial colours.

However all mine small stuff are equipped with reflection tape or glow-in-dark and reflective cord. I had search for mine stuff too often...
