Colour and emotion
The colours of anger
Red is the colour of anger in most languages and studies, from 'seeing red' to Hindi's 'laal-peela'. Black comes second.

Anger is red. The link shows up in surveys on every continent, in idioms in dozens of languages, and in the face itself, which flushes in many people when they are furious. Black is the usual second choice, for a darker, colder rage. This is one of the better supported pairings in colour research, and one of the few with a plausible bodily cause. Still, red is not only anger. The same colour means love, luck or loyalty depending on where and how it appears.
What studies find
In the 2025 review by Jonauskaite and Mohr, red was linked to anger in roughly three quarters of the studies that tested it, with black next. A five-nation study led by Ralph Hupka in 1997 found red and black tied to anger in Germany, Mexico, Poland, Russia and the United States. Experiments by Adam Fetterman and colleagues found that people thinking about anger were quicker to see red. One hypothesis is that primate colour vision is tuned to changes in blood under the skin, which would make a flushed face a readable signal. That idea is debated. The association itself is not.
In language
English speakers 'see red'. So do Germans (rotsehen) and the French (voir rouge). In Hindi a furious person turns 'red and yellow' (laal-peela hona). Chinese describes a quarrel as 'red face, thick neck', and Japanese says someone is angry until bright red (makka ni natte okoru). Black has its share. French has 'black anger' (colère noire), German speakers can annoy themselves black (sich schwarz ärgern), and English has the black mood. English also offers 'purple with rage'. The phrase 'red rag to a bull' is misleading as biology: bulls cannot tell red from green and charge at the movement of the cloth.
Around the world
Red does not mean anger everywhere it appears. In Chinese opera a red painted face marks a loyal and brave character. In India the Natyashastra, the ancient treatise on drama, assigns red to raudra, the mood of fury. Kathakali dance drama in Kerala follows a similar logic: violent, destructive characters wear a red beard. In Tibetan Buddhist painting, wrathful protector deities are often dark blue, black or red, and their fury is understood as compassion in a fierce form. In Hupka's study, Polish respondents linked anger with purple as well. The red and anger link is wide, but local codes can overrule it.
Where it is used
Signals borrow from anger's colour. The red card in football, first used at the 1970 World Cup, came from the English referee Ken Aston, who took the idea from traffic lights. Stop signs, error messages and alarm lights are red. Cartoons and emoji turn an angry face red, and the character Anger in Inside Out is a red block who bursts into flame. Protest movements use red for militancy. Because red raises alertness in so many settings, designers avoid large areas of saturated red where people need to stay patient, such as waiting rooms and long forms.
Anger in colour, place by place
The Natyashastra, the classical Sanskrit treatise on drama, gives each mood a colour. Raudra, fury, is red.
In Kathakali dance drama from Kerala, a red beard (chuvanna thadi) marks violent and destructive characters, while noble heroes have green faces.
In Hindi and Urdu a furious person is said to turn 'red and yellow', laal-peela hona.
French speaks of 'black anger', colère noire, and German of annoying oneself black, sich schwarz ärgern.
In a 1997 five-nation study, Polish respondents linked anger, envy and jealousy with purple, unlike the other groups asked.
The football red card was devised by English referee Ken Aston and first used at the 1970 World Cup in Mexico.
