Political colours are colours used to represent a political party, either officially or unofficially. Parties in different countries with similar ideologies sometimes use similar colours. For example, the colour red symbolises left-wing ideologies in many countries (c.f. Red Flag, Red Army, Red Scare). However, the political associations of a given colour vary from country to country; for example, red is also the colour associated with the conservative Republican Party in the United States.

- 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 less militant than socialism.
- Some European liberal parties use pink or magenta as their party colour. Examples include the Danish Social Liberal Party and NEOS – The New Austria.

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. 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 labor 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.

Since about the year 2000, the mass media have associated red with the Republican Party, despite the fact that the Republican Party is a conservative party. (See Red states and blue states.) The use is probably entrenched, as many political organisations (for example the website RedState) now use the term.
- The opposite in the case of Puerto Rico, as the liberal Popular Democratic Party uses red.
In India, saffron is traditionally associated with Hinduism, Hindutva and the Hindu nationalist movement. Saffron was chosen because in Hindu Sanatana Dharma, 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. Later it was used by the Czarist Whites who fought against the communist "Reds" in the Russian Civil War, because the Russian "Whites" had similar goals to the French "Whites" of a century earlier.
- 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 the United States the two major political parties use the national colors – 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. In the weeks following the 2000 election, however, 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, however, 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.
