With everything else, it depends. I used to be a camo all the way kinda guy. But, becoming a scout leader has help me see the other side. For my scouts, I make sure all their tent tie outs are as bright as possible. I also spray paint the top of their tent pegs with hunter orange spray paint. Of course, the tent body's color doesn't really matter when it comes to boys running into it cause they can't see it.
Incidentally, I have a ACU camo tarp for my hammock. I have been taking pictures of it for the last 2 years at every campsite I have pitched it. It hasn't blended in to any of them. Basically, it is a terrible camouflage. Hopefully the Army will get rid of it soon.
