A flag has come into existence centuries ago to serve a fundamental purpose which is to signify territorial boundaries. It is also designed to show or declare what territory or country it represents.It may be just a simple fabric that is raised or waved thru a pole, it can be hung as high as possible in order that people can see it from far distance. For those people who can see it from afar, aside that it signifies what territory the flag is at it can also describe the kinds of people who are within that territory.
Nowadays, flags are used for many purposes but the most common is to show honour and pride to the territory it represents, whether those are state flags or international flags. In America, each of the fiftystates has its own distinctive flag. Flags like these are usually seen at all government-owned buildings and at most schools too. These flags are uniquely designed and colors differ as well.
An example of this is the Colorado state flag. It plays with four colors. The two blue stripes represents the skies of the state, one white stripe represents the snow capped mountains, the red colored letter C stands for the name of the state itself. There is a golden colored disk inside the letter C that represents sunny abundance. Just like the Colorado flag, colors have relevance to the territories that flags represent. Even if the state has its own flag, the American flag must also be raised as a sign of pride and respect to their mother country.
