One common use of red as an additive primary color is in the RGB color model. Because "red" is not by itself standardized, color mixtures based on red are not exact specifications of color either. In order to produce exact colors the color red needs to be defined in terms of an absolute color space such as sRGB. As used in computer monitors and television screens, red is very variable, but some systems may apply color correction (so that a standardized "red" is produced that is not in fact full intensity of only the red colorant).

Etymology and definitions

The word red comes from the Old English read. Further back, the word can be traced to the Proto-Germanic rauthaz and the Proto-Indo European root reudh-. This is the only color word which has been traced to an Indo-European root.^[4] In the English language, the word red is associated with blood, certain flowers (i.e. roses), and ripe fruits (i.e. apples, cherries). Fire is also strongly connected, as is the sun and the sky at sunset. Healthy persons are often said to have a redness (as opposed to appearing pale). After the rise of socialism in the mid-19th century, red was to describe revolutionary movements. The word is also obviously associated with anything of the color occupying the lower end of the visible light spectrum, such as red hair or red soil. Red Indians is a British term for Native Americans, American terms for this ethnic group include redskin and red man, though they are not the preferred terms.^[5] Old English (also called Anglo-Saxon[1], Old English: ) is an early form of the English language that was spoken in parts of what is now England and southern Scotland between the mid-fifth century and the mid-twelfth century. ...

Animals and plants

• When used about animal coloration red usually refers to a brownish, reddish-brown or ginger color. In this sense it is used to describe coat colors of reddish-brown cattle and dogs, and in the names of various animal species or breeds such as red fox, red squirrel, red deer, Robin Redbreast, Red Grouse, Red Knot, Redstart, Redwing, Red Setter, Red Devon cattle etc. The usage for animal color appears similar to that for red ochre, red hair and Red Indian. Interestingly red appears to be rarely used in names of animals which are a brighter blood-red or scarlet color (Carmine Bee-eater, Scarlet Tanager).

• When used for flowers, red often refers to purplish (red deadnettle, red clover, red helleborine) or pink (red campion, red valerian) colors.

• A red filter used in black and white photography increases contrast in most scenes. For example, combined with a polarizer, it can turn the sky black. Films simulating the effects of infrared film (such as Ilford's SFX 200) do so by being much more sensitive to red than to other colors.

Symbolism

Sin, guilt, and passion

Red is frequently used as a symbol of guilt or sin, often as connected with blood.^[7] A biblical example is found in Isaiah: "Though your sins be as scarlet, they shall be white as snow."^[8] Also, The Scarlet Letter an 1850 American novel by Nathaniel Hawthorne, features a woman in a Puritan New England community who is punished for adultery with ostracism, her sin represented by a red letter 'A' sewn into her clothes.^[9] This all comes from a general Hebrew view inherited by Christianity which associates red with the blood of murder, as well as with guilt in general.^[10] Another popular example of this is in the phrase "caught red-handed", meaning either caught in an act of crime or caught with the blood of murder still on one's hands.^[5] At one point, red was associated with prostitutes, or now, with brothels (red-light districts).^[11][12] Statistics have shown that red cars are more likely to be involved in accidents.^[13] Red may also represent the deadly sin wrath. Satan is usually depicted as colored red and/or wearing a red costume in both iconography and popular culture.^[14] This article is about the 1850 book. ...

The color red is associated with lust, passion, love, and beauty as well. The association with love and beauty is possibly related to the use of red roses as a love symbol.^[15] Both the Greeks and the Hebrews considered red a symbol of love, as well as sacrifice.^[16]

Courage and sacrifice

Red is also used as a symbol of courage and sacrifice, as in blood spilt in sacrifice or courage in the face of lethal danger.^[17] Examples of this are found in the flags of many nations including the United States, as well as in the novel The Red Badge of Courage, in which a soldier in the American Civil War discovers the meaning of courage.^[18] Besides the association with guilt previously mentioned, in Christianity, red represents the color of Christian martyrs who suffered death for their faith. It is sometimes used for Holy Thursday and during Eastertide. In Roman Catholic tradition it is used for all feast days of Christian martyrs as well as Palm Sunday in anticipation of the death of Jesus. Along the same lines, red is associated in Roman mythology with the god of war, Mars.^[17] A Roman general receiving a triumph had his entire body painted red in honor of his achievement.^[19] The phrase "red-blooded" describes someone who is audacious, robust, or virile^[5] In English heraldry, red (called gules) denoted ardent affection or love, while crimson (blood-color) stood for boldness, enthusiasm, or impetuosity.^[20] Psychics who claim to be able to observe the aura with their third eye report that someone with a red aura is typically someone who is in an occupation requiring vibrant health and vigorous physical exertion, such as a professional sportsperson, a personal trainer, or a manual laborer.^[21] The Red Badge of Courage (1895) is an impressionistic novel by Stephen Crane about the meaning of courage, as it is discovered by Henry Fleming, a recruit in the American Civil War. ...

Red catches people's attention, and is often used either in a negative way to indicate danger and emergency, or in a positive way in advertising to gain more viewers, or in nature, as a ripe fruit announces its readiness with its red color.^[22] Several studies have indicated that red carries the strongest reaction of all the colors, with the level of reaction decreasing gradually with orange, yellow, and white, respectively.^[23] Because of this, scientists have repeatedly recommended red for warning signals, labels, and signs. Because of these recommendations, red has seen widespread use as a danger signal, in stop signs, to warn people of extreme heat or flammability, and even to signal warnings in sports such as soccer.^[24] It may also represent fire and so may symbolize the presence of God. It is the liturgical color for Pentecost.

Flags

Red is one of the most common colors used on national flags throughout the world. On these flags it carries the same meanings which it does anywhere else: the blood, sacrifice, and courage of those who defended their country, the sun and the hope and warmth it brings, and the sacrifice of Christ's blood (in some historically Christian nations) are a few examples. Red is the color of the flags of several countries which once belonged to the former British Empire. The British flag bears the colors red, white and blue. red is represented by two crosses, the St. George's Cross and the diagonal cross of St. Patrick's Flag. The United States flag bears the colors of Britain, and other countries' flags, such as those of Australia and Fiji, carry a small inset of the British flag in memory of their ties to that country.

It was also used by Garibaldi's camicie rosse ("redshirts") in the Italian Risorgimento, and taken up by Leftist and generally revolutionary 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.
