Every countries national flag has there own pride, it depicts the history of a country and is considered as pride, a unique figure with distinct symbols and character which represents a country to be proud of. If we look at the flags of different country it might be confusing with similar color and designs, it does not quantify the definition of a unique symbol rather it confuses. Most of the national flags are rectangular in shape and are made of three colors.
