Red is a color at the highest frequencies of light discernible by the human eye. Red light has a wavelength range of roughly 630-760 nm. Lower frequencies are called infrared, or far red.

Red is an additive primary color, complementary to cyan. It was once considered to be a subtractive primary color, and is still sometimes described as such in non-scientific literature; however, the colors cyan, magenta and yellow are now known to be closer to the true subtractive primary colors detected by the eye, and are used in modern color printing.

Usage, symbolism, colloquial expressions

  • Red catches people's attention, and is often used to indicate danger or emergency.
    • Red is the color of heat and fire. Taps for hot water are often labeled red. Red is commonly the color of fire alarm boxes, fire extinguishers, and the firefighter profession itself.
    • Red denotes "stop" in, for instance, stop signs, traffic signals, brake lights, or the flashing lights of a school bus.
    • A Red Cross, Red Crescent or Red Crystal flag signify medical personnel, facilities, or equipment, or the Geneva Conventions.
    • Red indicates extreme danger on Western color-coded scales, such as wildfire hazard signs or the U.S. Homeland Security Advisory System.
    • In auto racing, a red flag signals all cars to immediately stop. The redline is the maximum speed an engine and its components can safely run.
    • Emergency exits on passenger aircraft are indicated by red signs and lighting.
    • "Redlining" is delineating a forbidden area (as on a map), for instance where a company denies or increases the cost of services, and is illegal in various circumstances in the U.S.
    • With ships on collision courses, the ship on starboard tack sees the Green for Go light on the ship on port tack, while the ship on port tack sees the Red for Stop light on the ship on starboard tack.
  • In Western religion, red represents the color of fire and so symbolizes the presence of God. It is the liturgical color for Pentecost. It is also considered the color of the Church, since red can also symbolize the blood of martyrs. It is sometimes used for Holy Thursday and during Eastertide. In Catholic tradition it is used for Palm Sunday in anticipation of the death of Jesus.
  • In the original Star Trek series, red uniforms are for engineering and security personnel. (On away missions, ensigns in red uniform would often get killed - see Redshirt (science fiction)). For Star Trek: The Next Generation onwards, red uniforms are for command personnel.
  • In the Power Rangers and Super Sentai series, the Red Ranger is usually the leader of the team.
  • In the Star Wars universe, red is traditionally (although not always in the Expanded Universe) the color of light saber used by the Sith, evil users of the Force. This is because a red light saber crystal is synthetically made, and therefore separated from the natural world. A red crystal is supposed to be stronger.
  • In Association football (soccer), the referee shows a red card to a player who is being sent-off.
  • Red can sometimes symbolize evil in any kind of work that involves a villain.
  • Being the color of blood, red was associated with the Roman mythology god of war, Mars, and the reddish planet Mars became named after him. The phrase "red-blooded" describes someone who is audacious, robust, or virile; it is sometimes used to contrast with a cold or effete "blue blood" although the terms are unrelated in origin.
  • Red is the color of sex and romance, (because of its association with blood, which is responsible for arousal) thus the red of a Valentine heart and of a "red-light district". Paradoxically, it also denotes anger, as in the expression seeing red, or embarrassment, as in being red-faced (many of these effects themselves caused by the blood rushing to the brain from adrenaline).
  • Red is considered holy in some parts of sub-sahara Africa. In these regions women are forbidden to wear red clothes.
  • In English heraldry, red (called gules) denoted ardent affection or love, while crimson (blood-color) stood for boldness, enthusiasm, or impetuosity. (The American Girls Handy Book, p. 369-370)
  • Before the French revolution red was the color of the flag signifying the imposition of martial law.
  • Beginning with the Revolution of 1848, "Socialist" red was used as a color of European Revolutionaries, often in the form of the red flag. It was also used by Garibaldi's camicie rosse ("redshirts") in the Italian Risorgimento, and taken up by Leftist and generally radical groups, while the white of legitimist Bourbon partisans became associated with pre-World War I conservatives. This relates to the term "Blood of the workers", representing the suffering of the proletariat.
