The National Flag is a horizontal tricolour of India saffron (kesaria) at the top, white in the middle and India green at the bottom in equal proportion. The ratio of width of the flag to its length is two to three. In the centre of the white band is a navy-blue wheel with 24 equally spaced spokes which represents the Ashoka Chakra.
The design of the National Flag was adopted by the Constituent Assembly of India on 22 July 1947.
