THE NATIONAL FLAG OF INDIA is in tricolor ( TIRANGA).
Sister Nivedita was the author of the preliminary design for the Indian flag in 1906. Her conception consisted of a Vajra or a thunderbolt as the main symbol with the words Vande Mataram written on it. Madam Bhikaji Cama unfurled the first Indian flag of freedom in Stuttgart at the socialist congress meeting in the year 1907. Her flag had the sun, the moon, seven stars and the lotus with Vande Matram inscribed on the central white portion.
National Flag of India :
The Indian flag is a horizontal tricolor in equal proportion of deep saffron on the top, white in the middle and dark green at the bottom. The ratio of the width to the length of the flag is two is to three. In the center of the white band, there is a wheel in navy blue to indicate the Dharma Chakra, the wheel of law in the Sarnath Lion Capital.
This center symbol or the 'CHAKRA', is a Buddhist symbol dating back to 200th century BC. Its diameter approximates the width of the white band and it has 24 spokes, which intends to show that there is life in movement and death in stagnation. The saffron stands for courage, sacrifice and the spirit of renunciation; the white, for purity and truth; the green for faith and fertility.
The design of the National Flag of India was adopted by India's constituent assembly on July 22, 1947. It's use and display are regulated by a code. The flag symbolizes freedom. The late Prime Minister Pandit Nehru called it a flag not only of freedom for ourselves, but a symbol of freedom for all people.
It is important to explain the meaning of the three colors when we speak about the India flag. Saffron color represents courage and sacrifice, white is for peace and truth and green means faith and chivalry. The spinning wheel symbolizes the hope of the Indian masses.
A national protocol is supposed to be observed while displaying the national flag in India. The flag is supposed to be hoisted at sunrise and lowered at sunset except in special circumstances. It is also prohibited to show the Indian flag upside down and considered irreverent to keep the flag in a dirty and tattered mode.
