The tricolour flag was first designed during the Swadeshi Movement that took place in Bengal. It comprised of the three colours - red, green and yellow and eight lotuses - representing eight of British India, and a crescent moon – representing Hindus and Muslims. 3. The flag, later designed by Gandhiji, was also a tricolour, consisting of red, green and white colours and a spinning wheel in the centre - representing the Gandhian idea of self-help. The act of carrying the tricolour during the marches was considered to be a symbol of defiance.
