The word camouflage actually derived from the French word camoufler, which means to blind or veil. Military camouflage was spurred by the increasing range and accuracy of firearms in the 19th century. Today you can buy everything from camouflage bedding to camouflage purses, and even get camo wedding pictures, if that is your kind of thing.
During the second World War, the power of aerial observation and attack led every warring nation to camouflage targets of all types. Interestingly, animals use camouflage as well. For instance, squid can change their color to blend in with new surroundings, and most people are familiar with chameleons, which can blend in with their surroundings easily. In addition, the stripes on a zebra may seem like it makes it easy to see, but when they are moving it blurs their outline and confuses predators.
You can even find camo when you go to buy discount bathing suits. Whether it is camo bathing suits for women or camo bathing suits for men, you can find cheap camouflage bathing suits. Some people are really fans of the camouflage colored textile, and will do anything to find camo stuff anywhere.
