Flag of India

The National flag of India is officially described in the Flag Code of India as follows: "The colour of the top panel shall be India saffron (Kesari) and that of the bottom panel shall be India green. The middle panel shall be white, bearing at its centre the design of Ashoka Chakra in navy blue colour with 24 equally spaced spokes." ^[1] It was adopted in its present form during a meeting of the Constituent Assembly held on 22 July 1947, when it became the official flag of the Dominion of India. The flag was subsequently retained as that of the Republic of India. In India, the term "tricolour" (Hindi: तिरंगा, Tirangā) almost always refers to the Indian national flag. The flag is based on the Swaraj flag, a flag of the Indian National Congress designed by Pingali Venkayya.

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 (India saffron [Kesari in the code], white and India green) should be equal in width and length. The size of the Ashoka Chakra was not specified in the Flag code, but the Ashoka Chakra must have twenty-four spokes that are evenly spaced.^[6] 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.^[4] 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 color.^[6]^[4] Below is the list of specified shades for all colors 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 Color Specifications.^[4] The navy blue colour can be found in the standard IS:1803–1973.^[4]
