The two Os of the logo have been replaced by the postal stamp with an image of the Tricolour and New Delhi post mark in ink respectively.
The first letter of the logo is in saffron colour and the last two letters are in green colour, the colours of the national flag of India.
Ashoka chakra, in the center of the flag on white stripe, is the wheel of the 'dharma' or righteous living and dynamism. To me, Ashoka Chakra reminds to review our past, learn from it and collectively try to build better future for all of us as feeling proud to be an Indian.
It may be recalled that that the first stamp of independent India was issued for foreign correspondence in November 1947 depicting the Indian Flag and slogan of Jai Hind as shown in the doodle.
