How have colours been used to identify political and protest movements?

Political and protest movements across very different times and places have adopted specific colours as identifying symbols — from the UK suffragette movement's purple, white and green to the French Revolution's tricolour — each a specific, historically scoped choice, not a claim about what any colour means politically in general.

The Women's Social and Political Union, a leading UK suffragette organisation, adopted purple, white and green as its official campaign colours in the early 20th century.

United Kingdom · early 20th century

The blue-white-red French tricolour combined the traditional colours of Paris with the royal white following the French Revolution of 1789, and became France's enduring national flag.

France · 1789 onward

Red has been used as an identifying colour by a wide range of labour and socialist political movements since the 19th century, though red is also used by many unrelated political parties around the world.

Europe and beyond · 19th century onward

How a movement's colour is transmitted

Adopting a colour is the easy part; getting thousands of people to show it is the work. The records on this page show three channels. Merchandise: within two months of first appearing on its leaders, the suffragette sash was on sale to every member, with printed instructions for wearing it. Law: a flag flown by a group of rebels becomes the flag of a state when a constitution says so, as the Irish tricolour did in 1937. Reversal: a regime can remove a colour and a revolution restore it, as happened to the blue and red of the French flag between 1814 and 1830. A colour's political meaning lasts as long as one of these channels keeps carrying it. 1, 2, 3

Women's Social and Political Union	United Kingdom	from August 1908	London Museum	The tricolour sash, woven with 'Votes for Women', went on general sale and soon became an essential part of the suffragette 'uniform'; the union's newspaper urged members to wear it at all public events.	1

French republicans	Paris	25 February 1848	Élysée	Some of those proclaiming the republic wanted an entirely red flag. Lamartine answered that the tricolour had toured the world with the Republic and the Empire, while a red flag would be seen as the flag of a party.	3
Irish republicans, then the Irish state	Dublin	1916, 1922 and 1937	Department of the Taoiseach	The tricolour was flown over the General Post Office during the 1916 Rising, adopted as the flag of the Irish Free State in 1922 and formally confirmed as the national flag in the 1937 Constitution.	2

A popular generalisation, and what the evidence says

Generalisation: Red is the colour of the left.

Evidence: True of particular movements at particular times, and the 1848 episode shows red already read as a partisan colour in France. But red was also the crimson velvet of a British monarch's robe of state in 1840, and scarlet was the colour English judges kept 'for best'. The politics are in who adopts a colour and when, not in the colour. 3, 5, 6

Scope and caveats

These are accounts given by states and museums of their own flags and collections. They record official and curatorial views, which are not neutral on the events they describe.
Nothing here characterises the supporters of any movement, and no colour on this page identifies a person's politics.

Compare across traditions

Each of these is a separately scoped, separately sourced practice — shown together for comparison, not because they share one underlying meaning.

Purple, white and green in the UK suffragette movement

Historical — no longer current practice

United Kingdom · Women's Social and Political Union (WSPU) · early 20th century – 1918 (partial suffrage granted)

The Women's Social and Political Union (WSPU), a leading UK suffragette organisation, adopted purple, white and green as its official colours in the early 20th century, with purple representing dignity, white purity, and green hope — a deliberate branding choice by one organisation within the broader women's suffrage movement.

Not a universal rule: These were specifically the WSPU's own official colours, not a colour scheme used by every suffrage organisation in every country.
How this is changing: Purple, white and (sometimes) gold or green have been referenced by later women's-rights campaigns as a historical callback to this movement.

Blue, white and red in the French Revolution

Stable, widely documented

France · 1789

The blue-white-red cockade and later flag associated with the French Revolution combined the traditional colours of Paris (blue and red) with the royal white, and became the enduring national symbol of France following the Revolution.

Not a universal rule: The exact symbolism attributed to each colour has been described somewhat differently by different historians; the Paris-colours-plus-royal-white account is the most widely cited.
How this is changing: The tricolour has remained France's national flag since shortly after the Revolution, with only a brief interruption during the Bourbon Restoration.

Red in labour and socialist movements

Stable, widely documented

Europe and beyond · 19th century

Red has been used as an identifying colour by a wide range of labour, socialist and communist movements and parties since the 19th century, historically linked to imagery of workers' blood and revolutionary struggle — but red is also used by many other political parties and movements around the world with entirely different meanings.

Redmovement and party colour

Not a universal rule: Red is also the official colour of many centre-right, conservative and other parties in different countries (for example, several use red for entirely unrelated reasons) — the colour alone never reliably indicates a political position without naming the specific party or movement.
How this is changing: Red remains in use by labour and socialist parties in many countries today, alongside its unrelated use by other parties and movements worldwide.

Black, green and gold in the African National Congress flag

Stable, widely documented

South Africa · African National Congress (ANC) · 1912

The African National Congress (ANC), the South African liberation movement founded in 1912, adopted a black, green and gold flag — colours later incorporated into post-apartheid South Africa's own national symbolism — historically associated with the people, the land, and mineral wealth respectively in commonly cited accounts.

Not a universal rule: This is one political party's own flag and stated symbolism, described factually here — not an endorsement, and not the only liberation-movement colour scheme in South African history.
How this is changing: These colours remain in use by the ANC as a political party in contemporary South African politics.

Orange in Ukraine's 2004 political protests

Historical — no longer current practice

Ukraine · 2004 – 2005

Orange was the identifying campaign colour of Viktor Yushchenko's political camp during Ukraine's disputed 2004 presidential election, and mass protests that followed became widely known internationally as the 'Orange Revolution' — a specific historical episode, not a general or ongoing symbol of Ukrainian identity.

Orangecampaign and protest colour

Not a universal rule: This described a specific historical political campaign and protest movement at a specific time — it is not a general or ongoing description of Ukrainian national colour or identity, and Colourwise takes no position on the political events themselves.
How this is changing: Ukrainian political colour associations have continued to shift in the two decades since 2004, including in later, distinct political movements.

Green as the international environmental movement colour

Stable, widely documented

global · 20th century

Green became the internationally recognised colour of the environmental movement over the course of the 20th century — an intuitive association with plant life and nature that spread globally through environmental organisations, largely independent of green's separate religious and national associations elsewhere.

Greenenvironmental movement branding

Not a universal rule: This global environmental-movement use of green developed separately from, and should not be confused with, green's distinct religious significance in Islamic tradition or its use in Irish national identity.
How this is changing: Green remains the dominant international colour of environmental branding and political green parties today.
