The idea of being camouflaged is to blend in with your surroundings and obscure yourself visually as much as possible.
I was watching news of the latest overseas terrorist attacks when I saw troops wearing blue camouflage military uniforms. I'm not sure what country was wearing them, since the sound was muted, but I have to wonder – do the military leaders in this area know how to camouflage? I can't think of any types of terrain where blue camouflage would be a benefit. Forest/woods? Fail. Desert? Fail. Snow? Fail. Floating face down in water? Almost not fail. As far as I can tell, blue is definitely not the best camouflage choice one could make.
Maybe I'm missing something, but it seems to me that they're planning on fighting all of their battles in fields covered with blue violets.
