Survival and Emergency Preparedness

Do you carry anything in particular in your EDC, BOB or GHB that would help you to remain hidden or aid in stealth? What situation do you envision in which you'd want to be unseen or at least as totally gray man as possible?

My bednet is tan
My hammock is tan/black
I usually have a tan or camo tarp

Generally, just as a low visual impact in the woods thing. I like the woods to be the woods, not a neon green yellow and orange sherbet.
