I think the use or avoidance of camoflauge is just a matter of personal preference. Yes, it has definite associations with the military and with game hunting, but people vary widely in how they view the military and game hunting, so you can't control how they will view your camo tent, either.

I try not to worry about such stuff. My own preference is for duller sorts of colors for my tent (light green, light grey, pale yellow-white, or tan), but not actual camoflauge designs. Day-glo colors work better for smaller items that are more easily lost or overlooked. But that's just me. Suit yourself. HYOH.
