Deep saffron (गेरुआ या भगवा) is the color of the upper band of the Indian National Flag (Bharatiya Rashtriya Dhwaj). It represents sacrifice and salvation.
Saffron-colored cloth is thought by some to have a history of use among Celtic peoples. A "saffron" kilt is worn by the pipers of certain Irish regiments in the British Army and in the defence forces of the Republic of Ireland. This garment is also worn by some Irish and Irish-American men as an item of national costume. Its color varies from a true saffron orange to a range of dull mustard and yellowish-brown hues. The Antrim GAA teams are nicknamed "The Saffrons" because of the saffron-colored kilt which they play in. The surname "Cronin," which originated in County Cork, is derived from the Old Irish word crón, meaning saffron-colored.
Now when Dawn in robe of saffron was hastening from the streams of Okeanos, to bring light to mortals and immortals, Thetis reached the ships with the armor that the god had given her. (19.1)
In Sanatan Dharma (Hinduism), the color deep saffron is associated with sacrifice and salvation. Saffron or "Bhagwa" is often worn by "Sanyasis" who have left their home in search of the ultimate.
Buddhist monks in the Theravada tradition typically wear saffron robes (although occasionally maroon--the color normally worn by Vajrayana Buddhist monks--is worn). (The shade of saffron typically worn by Theravada Buddhist monks is the lighter shade of saffron shown above.)
Sikhs use saffron as the background color of the Nishan Sahib, the flag of the Sikh religion, upon which is displayed the khanda in blue[2].
The color at the top of the Indian National Flag is a color officially called deep saffron that is an orangeish shade of saffron. The color deep saffron represents the Hindus of India, the color India green represents the Muslims of India, and the white represents other religions. According to another theory Deep Saffron represents sacrifice and renunciation, Green represents prosperity, fertility, abundance and chivalry and White represents peace. The Chakra in the middle of the flag represent continuous progress and evolution.
