The Indian national flag, widely called the Tiranga (tricolour), is a horizontal rectangle of saffron, white and green in a 3:2 ratio, with a navy-blue Ashoka Chakra of 24 spokes centred on the white band. In its present form it was adopted by the Constituent Assembly on 22 July 1947, weeks before independence on 15 August 1947.
How the flag evolved before 1947
The flag Indians know today emerged from several decades of experimentation. From the early 1900s onward, activists, associations and individuals proposed a range of designs, and historians differ on the exact dating and authorship of some of them. What follows is a widely cited sequence, presented as a general outline rather than a settled, unanimous record.
An often-referenced early banner is the flag hoisted in Calcutta in 1906, described as having three horizontal bands with symbols and script. In 1907, a flag associated with Indian activists abroad was displayed in Europe. Over the following years, the Home Rule movement of the mid-1910s used a design combining Union features with stars and stripes-style bands, reflecting the constitutional-reform aims of that period.
A significant step came in the early 1920s, when a design featuring red and green bands with a spinning wheel (charkha) at the centre was proposed within Congress circles. The charkha was linked to the message of self-reliance and hand-spinning associated with the swadeshi movement. A white band was subsequently added, producing a three-colour arrangement with the wheel, and by 1931 the Congress adopted a tricolour of saffron, white and green with a charkha as its flag. Accounts of who suggested each modification vary between sources, and readers seeking depth should consult multiple histories rather than a single narrative.
Pingali Venkayya and the design lineage
Pingali Venkayya is the name most commonly associated with the conceptual design of the Indian tricolour. He is generally credited with developing and promoting a flag concept in the years around 1921, including studying flags of many nations and presenting design proposals to Congress leaders. Because the flag passed through several hands and revisions, historians describe the outcome as a collective evolution to which Venkayya made a central and documented contribution, rather than the work of one person in isolation.
When the flag was finalised for the independent nation in 1947, the charkha at the centre was replaced by the Ashoka Chakra. Contemporary accounts explain this as a move toward a symbol drawn from India's ancient heritage. The colours and their horizontal arrangement, however, carried forward the design lineage that had developed over the preceding decades.
The 1947 adoption
On 22 July 1947, the Constituent Assembly of India adopted the national flag in the form recognised today. Independence itself followed on 15 August 1947, the culmination of a long freedom struggle involving many individuals, movements and strands of thought. For 2026, note the frequently confused point covered on our dedicated explainer: 15 August 2026 is the 80th Independence Day, marking 79 completed years of independence. Whenever the day is discussed, that distinction is worth keeping straight.
The meaning of each colour
The government's own explanation of the flag assigns meanings to the three bands. These are the widely published interpretations; some popular retellings add further layers, but the following are the commonly cited associations.
| Element | Position | Commonly cited meaning |
|---|---|---|
| Saffron (Kesari) | Top band | Courage and sacrifice |
| White | Middle band | Peace and truth |
| Green | Bottom band | Faith and prosperity |
| Ashoka Chakra (navy blue) | Centre of white band | The wheel of law (dharma); 24 spokes |
It is worth noting that public figures over the years have offered additional or more secular readings of the colours, emphasising ideas such as service, unity and growth. These interpretations coexist in public discourse, and no single reading is treated as the only official one beyond the government's stated associations above.
Saffron
The saffron band sits at the top of the flag. It is most often described as representing courage and sacrifice, and in wider commentary it is also linked to strength and renunciation.
White
The central white band is generally associated with peace and truth. It also provides the field on which the Ashoka Chakra appears, giving the wheel visual prominence at the heart of the flag.
Green
The green band at the base is commonly connected with faith, fertility and prosperity. Some interpretations tie it to the land and its growth.
The Ashoka Chakra and its 24 spokes
At the centre of the white band is the Ashoka Chakra, a navy-blue wheel with 24 spokes. It is drawn from the wheel that appears on the abacus of the Lion Capital of Ashoka at Sarnath, an emblem of ancient India. The Chakra is generally explained as representing the wheel of dharma, or the wheel of law, conveying the idea of continuous movement and dynamism.
The 24 spokes are the subject of several symbolic explanations in popular literature, including associations with the hours of the day and with virtues or principles. These readings vary between sources and are not all officially codified, so they are best treated as widely shared interpretations rather than fixed doctrine. What is consistent across accounts is the number of spokes (24) and the identification of the wheel with the Sarnath capital.
- The wheel is navy blue, positioned centrally on the white band.
- It has 24 spokes, evenly spaced.
- It is derived from the Lion Capital of Ashoka at Sarnath.
- It replaced the earlier charkha when the flag was finalised in 1947.
Proportions, specifications and the Flag Code 2002
The flag's proportions are precisely defined. The overall shape is a rectangle with a length-to-height ratio of 3:2. The three bands are of equal width, and the Ashoka Chakra is centred within the white band. Manufacturing standards for the flag, including permitted materials and dimensions in specified sizes, are governed by national specifications.
The display and handling of the flag are addressed by the Flag Code of India, 2002, which consolidates the rules, conventions and practices relating to the flag. Separately, the Prevention of Insults to National Honour Act, 1971 addresses acts that dishonour the national flag and other national symbols. Because both instruments have been amended and interpreted over time, readers should always consult the official text published by the Ministry of Home Affairs (MHA) rather than relying solely on summaries.
Two points of terminology are commonly mixed up. On Independence Day the flag is hoisted, raised from the base of the pole. On Republic Day it is unfurled, already at the top and then opened. When a flag is worn out or damaged, it should be disposed of respectfully in line with prescribed methods; our separate guide on how to dispose of a national flag walks through this, and the Flag Code page above is the authoritative reference to check.

Why the flag's story matters in 2026
Understanding the flag's evolution, its colours and the meaning of the Ashoka Chakra adds context to how it is displayed each year. Whether you are marking the day at home or abroad, the same specifications and conventions apply, and the same legal framework governs respectful handling.
