A national flag is a flag that represents and symbolizes a country. The national flag is flown by the government of a country, but can usually also be flown by citizens of the country. A national flag is designed with specific meanings for its colours and symbols. The colours of the national flag may be worn by the people of a nation to show their patriotism, or related paraphernalia that show the symbols or colours of the flag may be used for those purposes.
The National Flag(तिरंगा , Tricolor) is a horizontal tricolour of deep saffron (kesaria) at the top, white in the middle and dark green at the bottom in equal proportion. The ratio of width of the flag to its length is two to three. In the center of the white band is a navy-blue wheel which represents the chakra. The design of a national flag may be altered after the occurrence of important historical events. The burning or destruction of a national flag is a greatly symbolic act.
The top saffron colour, indicates the strength and courage of the country. The white middle band indicates peace and truth with Dharma Chakra. The green shows the fertility, growth and auspiciousness of the land.
Its design is that of the wheel which appears on the abacus of the Sarnath Lion Capital of Ashoka. Its diameter approximates to the width of the white band and it has 24 spokes. The design of the National Flag was adopted by the Constituent Assembly of India on 22 July 1947
Design and construction details
According to the Flag code of India, the Indian flag has a ratio of two by three (where the length of the flag is 1.5 times that of the width). All three stripes of the flag (saffron, white and green) are to be equal in width and length. The size of the Ashoka Chakra is not specified in the Flag code, but it has twenty-four spokes that are evenly spaced. In section 4.3.1 of “IS1: Manufacturing standards for the Indian Flag”, there is a chart that details the size of the Ashoka Chakra on the nine specific sizes of the national flag. In both the Flag code and IS1, they call for the Ashoka Chakra to be printed or painted on both sides of the flag in navy blue. Below is the list of specified shades for all colours used on the national flag, with the exception of Navy Blue, from “IS1: Manufacturing standards for the Indian Flag” as defined in the 1931 CIE Colour Specifications with illuminant C. The navy blue colour can be found in the standard IS:1803-1973.
