The Indian flag is a horizontal tricolour in equal proportion of deep saffron on the top, white in the middle and dark green at the bottom. In the centre of the white band, there is a wheel in navy blue with 24 spokes called the Dharma Chakra or Ashok Chakra. The ratio of the width to the length of the flag is 2:3.
The colour scheme seems to imply a meaning to the national flag of India. The saffron stands for courage, sacrifice and the spirit of renunciation; the white, for purity and truth; the green for faith and fertility. According to History, the design of the National Flag of India was adopted by India's constituent assembly on 22nd july, 1947.
