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."
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.
The flag, by law, is to be made of khadi, a special type of hand-spun cloth of cotton or silk made popular by Mahatma Gandhi. The manufacturing process and specifications for the flag are laid out by the Bureau of Indian Standards.
