Red
<nomobile>Template:DisplayImages</nomobile>
Red is any of a number of similar colors evoked by Template:Wiki consisting predominantly of the longest wavelengths of Template:Wiki discernible by the human eye, in the wavelength range of roughly 625-740 nm. Longer wavelengths than this are called infrared, or below red and cannot be seen by the naked human eye. Red is used as one of the additive primary colors of Template:Wiki, complementary to cyan, in RGB Template:Wiki systems. Red is also one of the subtractive primary colors of RYB Template:Wiki space but not CMYK Template:Wiki space.
In human Template:Wiki Template:Wiki, red is associated with heat, energy and Template:Wiki, and emotions that "stir the Template:Wiki", including anger, passion, and love.
Red is any of a number of similar colors evoked by Template:Wiki consisting predominantly of the longest wavelengths of Template:Wiki discernible by the human eye, in the wavelength range of roughly 630-700 nm. Longer wavelengths than this are called infrared, or below red and cannot be seen by human eyes.
Red's wavelength has been an important factor in laser technologies as red lasers, used in early compact disc technologies, are being replaced by blue lasers, as red's longer wavelength causes the laser's recordings to take up more space on the disc than blue lasers.[10] Red light is also used to preserve night vision in low-light or night-time situations, as the rod Template:Wiki in the human eye aren't sensitive to red. Red is used as one of the additive primary colors of Template:Wiki, complementary to cyan, in RGB Template:Wiki systems. Red is also one of the subtractive primary colors of RYB Template:Wiki space but not CMYK Template:Wiki space.
One common use of red as an additive primary Template:Wiki is in the RGB Template:Wiki model. Because "red" is not by itself standardized, Template:Wiki mixtures based on red are not exact specifications of Template:Wiki either. In order to produce exact colors the Template:Wiki red needs to be defined in terms of an absolute Template:Wiki space such as sRGB. As used in Template:Wiki monitors and television screens, red is very variable, but some systems may apply Template:Wiki Template:Wiki (so that a standardized "red" is produced that is not in fact full intensity of only the red colorant).
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. Red illumination was (and sometimes still is) used as a "safelight" while working in a darkroom, as it does not expose most photographic paper and some films. Though many more Template:Wiki darkrooms use an Template:Wiki safelight, red illumination is closely associated with the darkroom in the public mind.
Template:Wiki and Definitions
The word red comes from the Template:Wiki read. Further back, the word can be traced to the Template:Wiki rauthaz and the Proto-Indo Template:Wiki root reudh-.
This is the only Template:Wiki word which has been traced to an Template:Wiki root.
In Sanskrit, the word rudra means red. In the English language, the word red is associated with the Template:Wiki of Template:Wiki, certain flowers (i.e. roses), and ripe Template:Wiki (i.e. apples, cherries). Fire is also strongly connected, as is the Template:Wiki and the sky at sunset.
Healthy people are often said to have a redness to their Template:Wiki Template:Wiki (as opposed to be appearing pale). After the rise of socialism in the mid-19th century, red was to describe Template:Wiki movements. The word is also obviously associated with anything of the Template:Wiki occupying the lower end of the visible Template:Wiki spectrum, such as red hair or red soil.
Red Template:Wiki is a British term for Native Americans, American terms for this Template:Wiki group include redskin, redhead and red man, though they are not the preferred terms.
In Nature
In Template:Wiki, Template:Wiki of spectral type M (the Template:Wiki with the coolest temperature) are classified as red Template:Wiki.
Template:Wiki is called the Red Template:Wiki because of the reddish Template:Wiki imparted to its surface by the abundant Template:Wiki oxide Template:Wiki there. Astronomical objects which are moving away from the observer exhibit a red shift.
Jupiter's surface displays a Great Red Spot, a football-shaped area south of the planet's equator. Astronomers believe the spot to be some kind of storm.
Oxygenated Template:Wiki is red due to the presence of oxygenated hemoglobin.
Red light is the first to be absorbed by sea water, so that many Template:Wiki and marine Template:Wiki that appear bright red are black in their native habitat.
When used about animal coloration red usually refers to a brownish, reddish-brown or ginger Template:Wiki. In this sense it is used to describe coat colors of reddish-brown cattle and dogs, and in the names of various animal Template:Wiki or breeds such as red Template:Wiki, red squirrel, red Template:Wiki, Robin Redbreast, Red Grouse, Red Knot, Redstart, Redwing, Red Setter, Red Template:Wiki cattle etc.
The usage for animal Template:Wiki appears similar to that for red ochre, red hair and Red Indian.
Red appears to be rarely used in names of animals which are a brighter blood-red or scarlet Template:Wiki (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.
Aggression, anger, Template:Wiki, blushing, stop, Template:Wiki, courage, danger, guilt, energy, fire, hate, hell, honor, leadership, passion, socialism, sacrifice, Template:Wiki, sin, violence, negativity, warning.
A Template:Wiki example is found in Template:Wiki: "Though your sins be as scarlet, they shall be white as snow." Also, The Scarlet Letter an 1850 American Template:Wiki by Nathaniel Hawthorne, features a woman in a Puritan New England Template:Wiki who is punished for adultery with ostracism, her sin represented by a red letter 'A' sewn into her clothes. This all comes from a general Hebrew view inherited by Christianity which associates red with the Template:Wiki of murder, as well as with guilt in general.
Another popular example of this is in the phrase "caught red-handed", meaning either caught in an act of crime or caught with the Template:Wiki of murder still on one's hands. At one point, red was associated with Template:Wiki, or now, with brothels (red-light districts).
In Template:Wiki, red represents wrath, one of the Seven Deadly Sins. In Christianity, Satan is usually depicted as colored red and/or wearing a red costume in both iconography and popular culture. Statistics have shown that red cars are more likely to be involved in accidents.
The Template:Wiki 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. Both the Greeks and the Template:Wiki considered red a symbol of love, as well as sacrifice. Psychological research has shown that men find women who are wearing red more attractive.
Courage and Template:Wiki
Red is also used as a symbol of courage and sacrifice, as in Template:Wiki spilt in sacrifice or courage in the face of lethal danger. Examples of this are found in the flags of many nations including the United States, as well as in the Template:Wiki The Red Badge of Courage, in which a soldier in the American Civil War discovers the meaning of courage.
Besides the association with guilt previously mentioned, in Christianity, red represents the Template:Wiki of Christian martyrs who suffered death for their faith. It is sometimes used for Template:Wiki Thursday and during Eastertide, and red green and white is the Template:Wiki scheme of Template:Wiki. In Template:Wiki tradition it is used for all feast days of Christian martyrs as well as Palm Sunday in anticipation of the death of Template:Wiki.
Along the same lines, red is associated in Template:Wiki mythology with the god of war, Template:Wiki. A Template:Wiki general receiving a Template:Wiki had his entire body painted red in honor of his achievement.The phrase "red-blooded" describes someone who is audacious, robust, or virile.
In English heraldry, red (called gules) denoted ardent Template:Wiki or love, while crimson (blood-color) stood for boldness, enthusiasm, or impetuosity.
Warning
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 Template:Wiki with its red Template:Wiki. Several studies have indicated that red carries the strongest Template:Wiki of all the colors, with the level of Template:Wiki Template:Wiki gradually with orange, yellow, and white, respectively. 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.
In Religion
Red may represent fire and so may symbolize the presence of God.
In Christianity, red is the liturgical Template:Wiki for Pentecost. Also, in the Template:Wiki red is the Template:Wiki of a Template:Wiki.
In Template:Wiki red is the Template:Wiki for sacrificement and courage. Many Islamic states have it as a sign of the courage of Template:Wiki and the sacrifice of their lives for what is good.
In Metaphysics
In metaphysics red connects with the root chakra.
Template:Wiki developed a system called the Seven Rays, where she classified humans into seven different metaphysical psychological types, the "sixth ray" of "love-devotion" is represented by the Template:Wiki red. People who have this metaphysical psychological type are said to be "on the Red Ray".
Psychics who claim to be able to observe the aura with their third eye report that a red aura is associated with a love of sports and physical exercise.

In Non-Western Traditions
In China, red is the symbol of fire and the south (both south in general and Southern China specifically). It carries a largely positive connotation, being associated with courage, loyalty, honor, success, fortune, Template:Wiki, happiness, passion, and summer. In Template:Wiki Template:Wiki traditions, red is associated with Template:Wiki (where brides traditionally wear red dresses) and red paper is also frequently used to wrap gifts of money or other things. Special red packets called hong bao as in Mandarin or lai see as in Cantonese - are specifically used during the Chinese New Year to give monetary gifts. On the more negative end, obituaries are traditionally written in red ink, and to write someone's name in red signals either cutting them out of your life, or that they have died. Red is also associated with both the Template:Wiki yin and the Template:Wiki yang, depending on the source. When someone commits suicide, especially a Template:Wiki, and wants to haunt their loved one, they will dress in red from top to bottom before carrying out the act.
In Japan, red is a traditional Template:Wiki for a heroic figure.
In the Indian Sub-continent, red is the traditional Template:Wiki of bridal dresses, and is frequently represented in the media as a symbolic Template:Wiki for married women. The Template:Wiki is associated with Template:Wiki in marriage relationships through its connection to heat and Template:Wiki. It is also the Template:Wiki of wealth, beauty, and the goddess Lakshmi.
In Central Template:Wiki, Ndembu warriors rub themselves with red during Template:Wiki. Since their Template:Wiki sees the Template:Wiki as a symbol of life and health, sick people are also painted with it. Like most Central African cultures, the Ndembu see red as ambivalent, better than black, but not as good as white.[39] In other parts of Template:Wiki, however, red is a Template:Wiki of mourning, representing death. Because of the connection red bears with death in many parts of Template:Wiki, the Red Cross has changed its colors to green and white in parts of the continent.
