I now I saw something about this here but cannot find it using the search function.
My understanding is that having colored light (red, green, blue, etc.) can aid in tracking. I asked about that on another Yahoo Group and it was explained that if you use a light which is close to the color of the surface you are trying to track on, then tracks and their shadows stand out better. [Use green on grass, red on dry pine needles, yellow on sand, etc.]
I also recall someone saying blue makes blood show up better.
I thought I remembered Hacksaw having something to say about this. So, what's up with using colored light for tracking?
Thanks.
I think you are reading way too many end of society survival books and have an over active imagination as to what will likely be a survival situation a person will realistically encounter…
