Red is traditionally associated with 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 and Third 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. Sometimes these parties use pink instead, as a "moderate" colour instead of the more "radical" red, or "pink" used to describe the more moderate faction or membership within a left-wing party.
- Red is also the traditional colour of liberal parties in Latin America and was the colour use, for example, in Chile, Colombia, Costa Rica, Honduras, Mexico, Nicaragua and Uruguay for liberal parties. However, these parties follow social liberalism more than classic liberalism, thus seating in the centre-left.
- 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.

The PSOL and the Brazilian Socialist Party invert the traditional color schemes of left-wing political parties and use red as a secondary color with yellow being their primary color; the Socialists also use white as a main color. Along with pink, the Democratic Labour Party uses blue and white as main colors with red as a secondary color. In the context of left-wing politics, red is the main color of the Popular Socialist Party, a third way social democratic party which descends from the first incarnation of the Brazilian Communist Party.
- Also 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.

- 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. 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, socialists, liberals, 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.

The Christian democrats Lakas–CMD uses blue and gold, and the Nacionalista Party, while using the colours of the flag of the Philippines, had used green and lately orange, the preferred colour of 2010 presidential nominee Manny Villar. While popularly known as "reds", the left had not used that colour in elections, using instead purple or dark blue. Other parties use party colours sparingly.
- In Poland, of the two main parties; the populist-conservative Law and Justice (PiS) use blue and the centrist Christian-democratic Civil Platform (PO) uses orange. Of the other parties; the extreme-nationalist Kukiz'15 uses black, the populist-centrist Polish People's Party (PSL) uses green, the social democratic Democratic Left Alliance (SLD) uses red and progressive Razem uses purple.
- In Portugal, the centre-left Socialist Party (PS) use pink, on the centre-right Social Democratic Party (PSD) uses orange and the People's Party (CDS–PP) uses blue.
- In South Korea, the ruling conservative party Liberty Korea Party (former Saenuri Party) uses red as its colour, even though red is considered a leftist colour in Korea. In this case it is a kind of political strategy, to emphasise change and evolution.
- In Sweden, blue is used for the centre-right Moderate Party and liberal Liberals, while red is used for the Social Democratic Party, and socialist Left Party. Green is used by the Centre Party and the Green Party. The far-right Sweden Democrats uses yellow.
- In Taiwan, the leading groups of parties are the Pan-Blue Coalition, which leans more towards Chinese nationalism and the Pan-Green Coalition, which leans more towards Taiwanese independence. The New Party uses yellow as its party colour even though its policies are conservative; the Democratic Progressive Party uses green even though its international alignment is with the Liberal International and not the Green parties.
- In the United Kingdom (excluding Northern Ireland), the Conservative Party uses blue, the Labour Party uses red and the Liberal Democrats use gold and orange. The right-wing populist UK Independence Party has chosen to use the non-aligned colour purple. The British National Party (BNP) use the colours of the Union Jack, The centrist Social Democratic Party (SDP) used red and blue. The Scottish National Party (SNP) uses yellow and black and Plaid Cymru (PC) uses gold and green.
- 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. However, in the weeks following the 2000 election there arose the terminology of red states and blue states, in which the conservative Republican Party was associated with red and the liberal Democratic Party with blue. 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. In 2004, the association was mostly kept. 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, while blue is typically associated with right-wing politics.
- 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 the accounting world, red ink is used indicate a deficit (that is, spending exceeds income). Politicians often attack deficit spending as "being in the red." For example Republican presidential candidate Robert Dole in 1996 denounced one of President Bill Clinton's proposals because it would impose new costs on small business. Dole said: "Now that the federal government is running in the red and state governments are faced with budget deficits that rise each year, the Democrats are looking for a new pocket to pick, and small business will fill that role."
- In Puerto Rico, the three main parties are: Partido Nuevo Progresista (blue), Partido Popular Democrático (red) and Partido Independentista Puertorriqueño (green).
