I don't mind camo, but I don't use it myself.

Personally, I like my tent and pack to be at least a highly contrasting color to the environment I'm in. This mainly has to do with most of my camping being well off the beaten path.

In our thick forests here it's pretty easy to be less than 100 ft from your tent and not be able to easily see it, even in the bright of day.

My old pack is a sort of a dark olive drab color and it blends in too well here with the forest. There have been more than a few times I've set it down to go explore and went a bit further than I originally intended and had to do a bit of searching for my pack when I was done.

Now I tie blaze orange survey tape on it, that helps a lot, but if I were to buy a new one, and had a choice of colors, I'd choose something brightly colored even if it were ugly. Same thing with a tent or tarp.

I think that if I did most of my camping in designated sites, or near the trail, I'd prefer something more subtle.
