Years ago REI did tests of colors and decided a dark orangewas best for mountaineering tents- they were cheery and easy to find, butcut down on light more to help stave off snow blindness.Most folks that buy our shelters and fabric prefer-bright colors if they snow camp,navy, black, green or gray if they trail hike (to hide from the crowds),black or navy for desert for better shade with high pitch,orange or yellow for emergency shelters and search and rescue,yellow for river trips for mood enhancement on rainy days,blaze orange, green or gray for hunters (depending on the type of hunting military tactical)gray or green for those in bear country ( to avoid visually attracting them)photographers like a bit of color in their photos."
Wow.....great info. The comment about a grey tarp letting radiant heat through seems to jive with what we experienced. Sounds like a darker color would create better shade. However, the lighter color will work better on spring & fall trips when we need more light & rain protection.
Thanks to all for the input. And Old Gringo.....you are right, the best shade comes from a big old tree !!!!!!!!
