The Indian national flag was designed as a symbol of freedom. The late Prime MinisterJawaharlal Nehru called it "a flag not only of freedom for ourselves, but a symbol of freedom to all people." 
The Indian national 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 2:3. At the center of the white band, is a wheel in navy blue color that indicates the Dharma Chakra (the wheel of law). The wheel has 24 spokes. 
The saffron color in the flag stands for courage, sacrifice and the spirit of renunciation; the white, for purity and truth; and the green for faith and fertility.
