Parties in different countries with similar ideologies sometimes use similar colours. As an example the colour red symbolises left-wing ideologies in many countries (leading to such terms as "Red Army" and "Red Scare"), while the colour blue often used for conservatism, the colour yellow is most commonly associated with liberalism and right-libertarianism, and Green politics is named after the ideology's political colour.
The political associations of a given colour vary from country to country, and there are exceptions to the general trends. For example, red has historically been associated with monarchy or the Church, but over time gained association with leftist politics, while the United States differs from other countries in that conservativism is associated with red and liberalism with blue.
Black is primarily associated with anarchism (see anarchist symbolism). Black can be seen as a lack of colour, anarchism as a lack of a state. It is used in contrast of national flags, to instead represent universal anarchism. Black is used to a lesser extent to represent fascism (see blackshirts and Schutzstaffel) and jihadism (see Black Standard).
The colours black and red have been used by anarchists since at least the late 1800s when they were used on cockades by Italian anarchists in the 1874 Bologna insurrection, and in 1877 when anarchists entered the Italian town Letino carrying red and black flags to promote the First International. During the Spanish civil war the CNT used a diagonally half strip of black and red, with black representing anarchism and red representing the labour movement and the worker movement. The flag was quickly adopted by other anarchists, with the second colour used to distinguish specific anarchist philosophies: anarcho pacifism with white, green anarchism with green, anarcho-syndicalism and anarcho-communism with red, mutualism with orange, and anarcho-capitalism with yellow, while black alone typically represents Anarchism without adjectives.
During the golden age of piracy, the black flags of pirates such as Blackbeard and Calico Jack became popular symbols of piracy. The flags representing death and no quarter to those who did not surrender. The black flag of the jolly roger, used by Calico Jack turned into a popular and recognizable symbol of pirates, particularly of pirates of the Americas. The skull and bones also became a hazardous symbol to display poisons such as cyanide, Zyklon B and other toxic substances. The black flag of piracy would later influence the symbols of anarchism, such as the symbols of the Free territory and Kronstadt rebellion. The rise of internet piracy led to the symbols of the golden age of piracy becoming widely adopted, becoming the symbols of pirate sites such as the Pirate bay.

- It less frequently represents various kinds of populist parties. Such is the case in Austria, Germany, France, Portugal, Switzerland, Finland, Romania, Hungary, Slovakia, the Czech Republic and Turkey.
- Orange is often used to represent the mutualist current in anarchist politics, as a middle ground between pro-market currents such as anarcho-capitalism (associated with the colour yellow of liberalism) and anti-capitalist currents such as anarcho-syndicalism and anarcho-communism (associated with the colour red of communism and socialism).

- In Ukraine, orange was the colour of liberal groups that participated in the "Orange Revolution". This gave the colour orange a certain association with radical anti-authoritarian politics in some countries and it has been used as such by groups and organizations in the Middle East, for example in Lebanon, the Palestinian Authority, Egypt, Bahrain and Israel.
Pink is sometimes used by social democratic parties, such as in France and Portugal. The more traditional colour of social democracy is red (because social democracy is descended from the democratic socialist movement), but some countries have large social democratic parties alongside large socialist or communist parties, so that it would be confusing for them all to use red. In such cases, social democrats are usually the ones who give up red in favor of a different colour. Pink is often chosen because it is seen as a softer, less aggressive version of red, in the same way that social democracy is more centrist and capitalistic than socialism. This is also the origin of the colloquial term "pinko".[dubious ]
- In some European nations and the United States, pink is associated with homosexuality and the pink flag is used as a symbol in support of civil rights for LGBT people, it is commonly used to represent queer anarchism. Originating from Nazi German policy of appending pink triangles to the clothing of homosexual prisoners.

- In the Dominican Republic, the Dominican Liberation Party logo is a yellow five-pointed star on a purple background. It was originally a leftist party but today the party is seen gravitating towards a more centrist platform.
Red is often associated with the left, especially socialism and communism. The oldest symbol of socialism (and by extension communism) is the Red Flag, which dates back to the French Revolution in the 18th century and the revolutions of 1848. Before this nascence, the colour red was generally associated with monarchy or the Church due to the symbolism and association of Christ's blood. The colour red was chosen to represent the blood of the workers who died in the struggle against capitalism. All major socialist and communist alliances and organisations—including the First, Second, Third and Fourth Internationals—used red as their official colour. The association between the colour red and communism is particularly strong. Communists use red much more often and more extensively than other ideologies use their respective traditional colours.
- In Europe and Latin America, red is also associated with parties of social democracy and often their allies within the labour movement, a symbol of common solidarity among leftists.
- Red is also the traditional colour of liberal parties in Latin America and was the colour used, for example, in Chile, Colombia, Costa Rica, Honduras, Mexico, Nicaragua and Uruguay for liberal parties.
- In Canada, red is the colour of the Liberal Party of Canada.
- Red is the official colour of both the Spanish Socialist Workers' Party and the Communist Party of Spain. Being the Socialists a major party, and in order to avoid clash of colours, Communists, and their alliance United Left, voluntarily use dark red as customary colour.
- In the United Kingdom, Australia, New Zealand, and Ireland, red is also the colour of the labour movement and the Labour (spelled Labor in Australia) parties in those countries. The use of red as a symbol is referenced in the British Labour Party's anthem, The Red Flag.
- In Brazil, red combined with black and white was formerly associated with Brazilian nationalism. The first incarnation of the agrarianist-centrist Social Democratic Party, both incarnations of the Brazilian Labour Party (the first a social democratic party, the current a populist one) and the Brazilian Democratic Movement use this color scheme. Red, Black and White are associated with the three races which form the ethnic composition of Brazil: the Amerindians (Red), the Afro-Brazilians (Black) and White Brazilians.
- A key exception to the convention of red to mean socialism is the United States. Since about the year 2000, the mass media have associated red with the Republican Party, even though the Republican Party is a conservative party (see red states and blue states). This use is possibly entrenched, as many political organisations (for example, the website RedState) now use the term. Conservative parties such as the Liberal Democratic Party of Japan and the People Power Party of South Korea also adopted red as their political colour in recent years.
Saffron is traditionally associated with Hinduism, Hindutva and the Hindu nationalist movement. Saffron was chosen because in Hinduism, the deep saffron colour is associated with sacrifice, religious abstinence, quest for light and salvation. Saffron or "Bhagwa" is the most sacred colour for the Hindus and is often worn by Sanyasis who have left their home in search of the ultimate truth.
- Historically, it was associated with support for absolute monarchy, starting with the supporters of the Bourbon dynasty of France because it was the dynasty's colour. Partly due to this association, white also came to be associated with Jacobitism, itself allied with the Bourbons. White cockades, white ladies' gloves, and Rosa pimpinellifolia (the 'burnet' or 'Stuart' rose) symbolised support for the exiled House of Stuart. Later it was used by the Whites who fought against the communist "Reds" in the Russian Civil War, because some of the Russian "Whites" had similar goals to the French "Whites" of a century earlier (although, it is worth noting that the Whites included many different people with many ideologies, such as monarchists, liberals, anticommunist social democrats and others).
- Because of its use by anti-communist forces in Russia, the colour white came to be associated in the 20th century with many different anti-communist and counter-revolutionary groups, even those that did not support absolute monarchy (for example, the Finnish "Whites" who fought against the socialist "Reds" in the civil war following the independence of Finland). In some revolutions, red is used to represent the revolutionaries and white is used to represent the supporters of the old order, regardless of the ideologies or goals of the two sides.
- In Italy a red cross on a white shield (scudo crociato) is the emblem of Catholic parties from the historical Christian Democracy party.
- In Afghanistan, the Taliban reversed the Islamist schema, using black shahada on a white background (symbol of purity).
- In the politics of the United Kingdom, white represents independent politicians such as Martin Bell.
- In Latin America, it is not unusual for left-wing social democratic parties to use yellow, as red was the traditional colour of liberals, especially in countries with prominent red-using liberal parties like Uruguay, Honduras, Mexico, Colombia and Costa Rica.
- Yellow is also associated with Judaism and the Jewish people, although this may be seen negatively (see also Yellow badge) and since 1945 the blue Star of David is preferred.
- In East and Southeast Asia, yellow is used to represent monarchies. For instance, in Thailand yellow represents King Bhumibol. It was also the colour of the pro-monarchy Panchayat system in the Kingdom of Nepal.
- It is also a common colour to represent Buddhism, monks in Burma used it in the anti-government protests.
- In Brazil, yellow, combined with green, is associated with right-wing populists and national conservatives movements against corruption, anti-Workers Party, anti-communists, supportive of impeachment of Dilma Rousseff and later, with support of Jair Bolsonaro, like PSL and the Alliance for Brazil. The association came because many of the protesters against Dilma wore the jersey of Brazil national football team, which is yellow with the numbers and some details in green, and because the protesters chanted that the Brazilian flag "will never be red" (in reference to the colours of the communism and Workers' Party) and "will always be green and yellow".
- In Hong Kong, yellow represents the pro-democracy supporters.
- In Malaysia, yellow was used by Bersih (The Coalition for Clean and Fair Elections).
- In the Philippines, yellow is commonly associated with the center to center-right Liberal Party although other colors such as red and blue are used.
- In South Korea, yellow associated with historically Uri Party and former President Roh Moo-hyun supporters.
- In Spain, regionally:
- Yellow is the colour used by supporters of the Catalan independence movement. Since 2017, separatists adopted the yellow ribbon as one of their symbols along with the estelada (pro-independence flag).
- Yellow is the customary colour of Canarian nationalism, with blue and white, the other colours in the flag of the Canary Islands, also being used.
- In the United States, the colour yellow was the official colour of the suffrage movement of the late 19th and early 20th centuries. In the 21st century, the Libertarian Party's official branding colours are gold-yellow, grey, and black. The gold-yellow colour is prominent because of the historical association with classical liberalism and in reference to a gold-backed currency and free markets.
Notable national political colour schemes include:
- In Northern Ireland, the Unionist parties in the Northern Ireland Assembly are called the "orange block" and the Nationalist parties are the "green block".
- Some of the established political parties use or have used different colour variations in certain localities. This was common in British politics up to the 1970s. The traditional colour of the Penrith and the Border Conservatives was yellow, rather than dark blue, even in the 2010 election Conservative candidates in Penrith and the neighbouring constituency of Westmorland and Lonsdale wore blue and yellow rosettes. In North East England, the Conservatives traditionally used red, Labour green and the Liberals blue and orange. In parts of East Anglia, the Conservatives used pink and blue, whilst in Norwich their colours were orange and purple. The Liberals and Conservatives used blue and red respectively in West Wales, while in parts of Cheshire the Liberals were red and Labour yellow. During the 18th and 19th centuries, the Tories used orange in Birmingham, pink in Whitby and red in East Worcestershire, whilst the Whigs were blue in Kendal, purple in Marlborough and orange in Wakefield. The traditional colour of the Warwickshire Liberals was green, rather than orange.
- In the United States the two major political parties use the national colours, i.e. red, white and blue. Historically, the only common situation in which it has been necessary to assign a single colour to a party has been in the production of political maps in graphical displays of election results. In such cases, there had been no consistent association of particular parties with particular colours. Between the early 1970s and 1992, most television networks used blue to denote states carried by the Democratic Party and red to denote states carried by the Republican Party in presidential elections. A unified colour scheme (blue for Democrats, red for Republicans) began to be implemented with the 1996 presidential election; in the weeks following the 2000 election, there arose the terminology of red states and blue states. Political observers latched on to this association, which resulted from the use of red for Republican victories and blue for Democratic victories on the display map of a television network. As of November 2012, maps for presidential elections produced by the U.S. government also use blue for Democrats and red for Republicans. In September 2010, the Democratic Party officially adopted an all-blue logo. Around the same time, the official Republican website began using a red logo.
- This association has potential to confuse foreign observers in that, as described above, red is traditionally a left-wing colour (as used with the Democratic Socialists of America), while blue is typically associated with right-wing politics. This is further complicated by the diversity of factions in the Democratic Party ranging from conservatives to right-libertarians to democratic socialists alongside the dominant centrist and social liberal elements of the party that outside the United States often each use different political colors.
- The conservative Blue Dog Coalition within the Democratic Party adopted the color blue at its founding, before the 2000 election solidified the red-blue convention.
- There is some historical use of blue for Democrats and red for Republicans: in the late 19th century and early 20th century, Texas county election boards used colour-coding to help Spanish speakers and illiterates identify the parties, but this system was not applied consistently in Texas and was not picked up on a national level. For instance in 1888, Grover Cleveland and Benjamin Harrison used maps that coded blue for the Republicans, the colour Harrison perceived to represent the Union and "Lincoln's Party" and red for the Democrats.
- In Puerto Rico, the main conservative party, unusually named the New Progressive Party, uses blue, while the Popular Democratic Party uses red and the Puerto Rican Independence Party uses green.
