Good comments!
I didn't specifiy exactly ...... the idea of using a
seasonal tarp for add'l cover where possible (between two trees), would be to divert rain or snow as it was suspended [by rope] between the trees.
Hopefully most "camps" would be in outta-the-way, hard to see locations.
Laying low and resting by day, traveling at night or low light would be the desired traveling technique especially if mobs were moving about (and any LEO dragnets). Along with a lightweight pop-up shelter (combined with) one's backpack, one's whole outfit would hopefully be kept as close to or under 20 pounds! (designing such provisions to be carried on foot, versus a hoss or big cushy sporty warm truck!

)
Where I live we have many types of cover (usually) unless one is in farmland which is flat and always VERY muddy. Skaget Valley (of Skaget Co, WA) is a somewhat vast valley that raises a huge number of flowers as well as local produce and grains. My state actually brags that it raises more tulips (and bulbs for export) than all of Holland combined! But I digress.
A generic pop-up tent or shelter methinks would be best with a brown, green, marsh grass, stubble-colored, or grey-of-some-kind background! Of course if one was able to "match" a camo pattern to his specific area, that would be ideal!
But when perusing fleeBay recently, I specifcally eliminated a handsome light blue tent from consideration (and any bright colored red, orande or yellow tents) because they show up just by glancing at the countryside!
I haven't used it often, but coloring golf balls or arrow veins (feathers)
SKY BLUE makes them incredibly easy to see against the ground! Making the arrows and golf balls easrier to find.
