I seem to recall there is a book by that same name.
Picture of a new AK47:
See, technology DOES work....
Maybe the frogies never heard of flat spray painting yer'ol hunt'n gun? They, the frogies, grow up hunting with poodles or something? Right? No need for a gun against a vicious, charging mushroom or fungus.
please excuse the emo music.
The interesting part of camouflage is the theory behind it.
This boils down to how the eyes, and by extension, sensor see, and how what is seen is interpreted.
This means that movement, sound, smell, size, shape, color, contrast, perspective, attraction, attention and fixation, expectation, suspense and shock, illusion—distraction and obscuration, and even superstition come into play.
To design camouflage, you have to understand the eyes, the ears, the nose, the brain, and the mind. Which is why is can be very, very expensive to develop camouflage that works.
The best camouflage not only blends in with its surroundings, but it actually repels interest. People do not want to look at it, yet at the same time want to neglect it. That blend is amazingly hard to achieve.
Maybe a good illustration can be found in a fake rubber dog poo gag.
Let’s say you use it to hide an important key.
If it’s up on a shelf, it is out of context, so most people would notice it and find the key.
If it was on the floor of your home, and you didn’t have a pet, you would likely inspect it and find the key.
If it was on the floor, and you had a pet that might make such a mess, you would still inspect it, carefully, but still find the key. Especially if the floor had other messes on it.
But if it was on somebody else’s floor, and they had a pet, and it was messy, you would probably leave it alone. But you would point it out to them, and they would find the key. Unless, of course, you didn’t like them, and you don’t mention it.
Ironically, even though it was very obvious, it might best be put someplace like a sidewalk, where it would be assumed to be natural and avoided.
In practice, aversion camouflage is peculiar. For example, if you wear an ordinary eye patch in public, people who don’t know you will only see the eye patch. Later, if asked, they will be hard pressed to remember any other detail.
