This is how children are taught to memorize the colors of the rainbow: everyone is red, the hunter is orange, wants to be yellow, to know is green, where is blue, sitting is blue, pheasant is purple.
Each color has a certain meaning, interpretation: some special feelings, traditions, ideas are associated with it.
There are not so many basic colors not to tell about them. At least the most interesting. Anyway, what seems interesting to me.
About the symbolism of color in various cultures, religion and heraldry.
The parade opens ...
1. White
Light, transparent glowing, colorless (in contrast to blue - dark, opaque). Clean as opposed to dirty.
Uncertainty and openness: the heroes of fairy tales want to see, to see the "white light". "White space" represented tax-free land, "white iron" - free from impurities, pure iron.
In divine language, white is the color of divine wisdom. In the mundane language, it symbolizes purity, chastity, peace, virginity, light, and since it “does not hide another color”, innocence and truth. According to the symbolism adopted by Catholics, it means innocence, joy and simplicity.
In the language of Catholic symbolism, transparent (cristalline) expresses the idea of \u200b\u200bimmaculate purity and clarity.
White magic is magic that uses its power for good, often for healing, or against evil and black magic.
White is most often associated with religious practices. Sacred horses in Greece, Rome, the Celts and Germans were white. In some areas of Southeast Asia, white elephants are considered sacred. The expression "white elephant" refers to large and imposing but useless acquisitions and comes from ancient Siam (Thailand). To get rid of the unwanted courtier, the king of Siam gave him a white elephant. The cost of feeding an elephant quickly ruined the courtier.
The white lily stands for purity and is a symbol of the Virgin Mary. The white rose also symbolizes virginity. In the ancient Roman temples of Vesta, the goddess of the hearth and the fire that burned in it, the Vestal priestesses who served there took a vow of virginity and wore white robes.
In the Christian church, white robes were worn for the consecration of churches. This is the color of baptism and communion, the holidays of Christmas, Easter and Ascension, as well as holidays in honor of saints who are not martyrs.
In the Orthodox Church, it is used in all divine services from Easter to Trinity Day, even at funerals.
The white flag is synonymous with surrender, truce, and in a broader sense - peace and goodwill. This custom is believed to come from ancient times, when, to demonstrate peaceful intentions and thus avoid attack, a white scroll or its symbolic representation - a white matter on a pole - was carried.
It also means blindness and absolute silence. In the East, it is the color of mourning. It was believed that if you wear black clothes, then the soul of the deceased will not see anything, hence it follows that white in mourning is light, vision, life (after life). Ghosts, disembodied creatures are usually depicted as whitish.
It also means cowardice. During wartime, in particular during the First World War, French people who avoided military service were sometimes given or sent white feathers.
It has been noticed that in cockfights the best fighting qualities are shown by roosters with scarlet and black colors. They pluck the feathers from the tails of their more cowardly white relatives, and these feathers have come to represent cowardice.
In heraldry, silver, called argent (agd), is depicted in black and white images in white.
2. Purple
Thin decay is thinning.
Purple tapestry.
To our waters and forests
The skies are falling.O. Mandelstam
The color of the spiritual worlds, the worlds of creativity. In the symbolism accepted by Catholics, purple is silence or contemplation. The angel, dressed in a purple robe, represented the ordinance of the priesthood.
In the symbolism of early Christianity, it meant humiliation, deep affection and sadness.
3. Blue
The word “blue” comes from “glow,” but unlike white, it is a dark, opaque, gloomy glow.
As the color of the clear sky and sea, it represents both height and depth. It also means constancy, devotion, justice, excellence, contemplation and peace. Ancient Egyptians blue was the same as truth. According to Hegel, it corresponds to meekness, the expression of a full mind and spiritual silence.
The Order of the Garter, the highest knightly order awarded by the British Crown, has a wide dark blue ribbon (it was established in 1348 by King Edward III).
The expression "blue stocking" in relation to the learned lady dates back to the 15th century, when a society of men and women engaged in the study of sciences gathered in Venice: blue stockings were a distinctive attribute of their costume. Parisian intellectuals borrowed this custom in the 1590s. The term originated in England in the 1750s, when a gentleman named Benjamin Stillingfleet began attending the evenings of the writer and social activist Mrs. Elizabeth Montague (she was dubbed the queen of the blue), donning blue stockings instead of the then fashionable silk black.
Blue symbolizes doubt and depression. Blues (blues, from English blue, - "blue") - predominantly melancholic slow tempo music that appeared in the American South in the late 19th century.
In Christian art, blue symbolizes piety, sincerity, prudence. It was originally adopted for worship, but is currently not required. It is sometimes used in Spain in masses and some other religious services.
In the angelic hierarchy, the cherub, since he is always immersed in godly thoughts, is represented in blue. In his book Dynamic Dissonance, Louis Danz writes that blue is most expressive for the Arabs, it is "the color of the material heavens that support the stars in their places."
In heraldry, blue is called azure (from the Arabic "azure"). Sometimes marked as "az" or marked with horizontal lines.
4. Blue
Father Pavel Florensky considers the symbolism of blue from the standpoint of the fact that there are three languages: divine, sacred and worldly.
In the divine language, blue is air, azure as a shade of the sky, the Holy Spirit and the eternal Divine truth, the heavenly world.
In cosmogonies, the world is created by Divine Wisdom, and therefore God the creator is always blue. Vishnu was born out of blue. Krishna is portrayed with a blue body. Just like the Supreme deity of Egypt, Knef.
Amun, the divine word of the Egyptians, was represented by the color blue, and as such it is represented in the Egyptian drawings. This color accompanied Zeus (Jupiter) and Hera (Juno) - the Greek and Roman deities of the heavens, who were believed to live above the clouds. Agni, the god of fire, sat on a red-horned blue ram.
In Exodus, blue, like the tone of a cloudless sky, symbolizes revelation. According to the book of Numbers, the Israelites were commanded to have a blue border on the edges of their dresses, which would remind them of God.
In the sacred language, it becomes a symbol of immortality, which means human, physical death, sadness and mourning. Blue robes were worn by priests during Great Lent, in China and other countries of the East it is the color of the dead, in Egyptian burial grounds there are a large number of blue figurines.
Azure represents rebirth, spiritual education of a person. Indicates the baptism of the Holy Spirit.
In mundane language, blue is equivalent to fidelity. Blue scarabs adorned the rings of Egyptian warriors. The angel in the sacrament of marriage was depicted in blue vestments, meaning trust and fidelity.
According to Goethe, this is the thinnest haze. He always brings the dark with him.
Symbolizes valor and excellence. The Blue Ribbon is awarded for excellence in a variety of fields: the Atlantic Blue Ribbon is awarded to the passenger liner that crossed the ocean fastest in both directions (owned by Queen Mary in 1935-1952, since 1952 owned by United States ). Likewise, the Cordon bleu (Blue Ribbon) was once the highest knightly award in France, the ancient Order of St Esprit (Holy Spirit).
Blue is associated with royalty and noble birth. The expression "blue blood" for people of high birth comes from the belief that the veins of the Spanish aristocrats are "bluer" than those of those who came from "mixed" marriages. Likewise, "true blue" emphasizes loyalty, perhaps on the basis that it was believed that true loyalty could only be shown by a person of aristocratic background.
For a newborn boy, they usually buy blue ribbons and a stroller, suits of blue color and its shades.
In the modern world, homosexuals are called "gay".
5. Green
The color of spring, new growth, fertility, nature, joy. Green very often signifies continuity and even immortality when, for example, we say "evergreen". In the symbolism of Catholic art, green was the color of hope, imperishable youth, and contemplative life. The angel in the sacrament of blessing (chrismation) was depicted in a green robe.
In cosmogonic symbolism, green indicates the world that is born in the bosom of primitive waters, and the first degree of initiation: baptism with water. It is a mixture of blue and yellow, green is a mystical color that makes a connection between the natural and the supernatural.
Green means abundance, prosperity, stability, because it is not for nothing that many states have chosen green shades for their money. But, on the other hand, green indicates a lack of money. In some European countries, bankrupts were required to wear a green hat.
At sea, a green flag signals a shipwreck. On the ground, this signal more often means "Movement allowed"; as a road signal green - "The way is clear", yellow or amber say: "Attention! “, And red -“ Stop! ". This value was standardized in Britain in 1893. Prior to that, green served as a warning, white allowed movement, and red prohibited.
Green is a sign of decay and mold. Osiris, god of dying and resurrecting nature, patron and judge of the dead, was depicted in green. In folklore, it is the color of the elves, hence the color of disobedience and leprosy. It also symbolizes envy and jealousy. As a symbol of youth, green is tantamount to immaturity, underage, inexperience, naivety.
In Christian churches, green is prescribed for worship in the period between Baptism and Trinity. Green is sacred in Islam.
On national flags, green is usually placed to emphasize the role of agriculture or the abundance of forests.
In heraldry, green is called "vert" (short for "vt"). With a monochrome image of the coat of arms, it was drawn with diagonal lines from the upper left corner to the lower right.
6. Yellow

In India, a newlywed woman covers her hands in yellow to show the happiness of union she is waiting for. According to Goethe, yellow is the closest to light, the first phenomenon of light in matter.
In the symbolism of early Christianity, yellow (gold) means glory, fertility, kindness. This corresponds to the earth.
It also has the opposite interpretation - as the color of betrayal, jealousy, lies and cowardice. According to the symbolism accepted by Catholics, it is a test of suffering or envy. In church art, Cain and Judas Iscariot were usually painted with yellow beards. In some Christian countries, Jews were portrayed in yellow robes because they "betrayed Jesus."
During World War II, in countries occupied by the Nazis, Jews were ordered to wear headbands with a yellow star, "headbands of shame." In medieval Europe until the 16th century, in some places the doors of houses of criminals and traitors were smeared with yellow paint.
Heretics, condemned by the Spanish Inquisition, were burned dressed in yellow, as a sign that they had betrayed God. Cowards were called "yellow-bellied" because it was believed that the coward's liver was devoid of blood and had a yellow (or white) color.

In the British Navy, the red flag as a "challenge to battle" has existed since the 17th century.
It has been the color of anarchy for the last two centuries.
The red flag is the banner of international socialism and the left wing in politics in general. The flag was used by the Communards of the Paris Commune of 1871.

9. Magenta
Indicates power, glory, honor, greatness, power.
As a combination of red and blue, it symbolizes the union of love and truthfulness. Since purple paint was the most expensive, purple represented gold. Among the ancient Romans and Greeks, only emperors, kings, generals, judges wore purple togas. Since then, purple has been associated with the throne and power. The expression "born in purple" in relation to all who belong to the upper class dates back to the days of the Byzantine Empire, where the rule was that a future emperor should only be born in a room with purple bedspreads on the walls.

We are all familiar from childhood with mnemonic rules - ways to memorize some facts with the help of seemingly completely unrelated phrases. The most striking example is, of course, “ TOevery ABOUThotnik Fwants Znat, Dde FROMwalking Fazan ”, a mnemonic for the arrangement of colors in a rainbow. In fact, mnemonics are widely used to memorize scientific facts and even medical procedures. Before you is a set of such mnemonics (sometimes in English), guess what areas of knowledge they relate to?
1. Oh Be A Fine Girl, Kiss Me (or in Russian: One Shaved Englishman Dates Chewed Like Carrots)
2. How I want a drink, alcoholic of course, after the heavy lectures involving quantum mechanics
3. Everything Now Understandable It Has Become, Physicist Zhamuchen Nauki Died (or more classic Good Physicists Have Studied Under Very Fine Teachers)
4. Whole Pineapple And Slice Of Souffle Today Is Actually My Lunch
There are not so many people in the world who easily remember everything and never complain about memory.
We have to remember something. We use pieces of paper, notebooks, mobile phones, computers, etc. But often you can use mnemonic techniques to memorize information.
Mnemonics or mnemonics is the art of memorization, a set of special techniques that facilitate memorization.
Special phrases or verses are used - memos.
Below is a collection of memos collected on the Internet. Memories from various fields of knowledge: physics, chemistry, mathematics, astronomy, Russian.
Memories
The most famous memos are about the colors of the rainbow. Let's start with them.
Rainbow
To memorize the sequence of rainbow colors, there are mnemonic phrases, the first letters of each word in which correspond to the first letters of the color name. Looking down the rainbow, from outside to inside the arc:
Red, Orange, Yellow, Green, Cyan, Blue, Purple.
The most famous memory of this kind is the phrase:
Every Hunter Wants To Know Where The Pheasant Sits.
Or:

Roygbiv - an acronym in English used to memorize the primary colors of the spectrum of light radiation.
This is the name of a fictional character, each letter of whose name corresponds to the first letter of each color of the rainbow:
Roy G. Biv (Red, Orange, Yellow, Green, Blue, Indigo, Violet)
Red - Red, Orange - Orange, Yellow - Yellow, Green - Green, Blue - Cyan, Indigo - Indigo, Violet - Purple. 
For better memorization, English-speaking children memorize the decoding of this acronym:

Sequence of latin letters on a chessboard (ABCDEFGH), (or the beginning of the Latin alphabet) - the phrase is used: "Artist Bimu Give a Compass, His Surname - Zhe-Ash".
The chess knight problem
It is necessary to go around the whole board with the knight in such a way as to visit each field exactly once. Both the solution itself and the memorization of the answer are a rather difficult task. To memorize the moves Grandmaster Vasily Panov composed a poem.
In each pair of words, a checkerboard field is encrypted: the first word is a column, the second is a row. For example: Scarlet Autumn - a1, Valuable Gifts - c2

In order to remember some meaningless sequence or composition of something, people have long been using mnemonic phrases or memos. So I decided to make a complete list of such phrases. So:
- TOevery ABOUThotnik Fwants Z nat, D de FROM walking F adhan (the first letters correspond to the colors of the spectrum).
Another variant: "How One Day Jacques the Bell-ringer City Broke the Lantern". - What do I know about circles (the number of letters in each word corresponds to the value of Pi - 3.1416).
Another variant: "This I know and remember perfectly -" pi "many signs are superfluous to me, in vain" (respectively 3.14159265358).
And here is the pre-revolutionary phrase: "Whoever jokingly wants to know the number soon, Pi already knows" (3,1415926536). - OVAL - a hint for memorizing the four largest rivers in Russia - ABOUTbi, INolgi, ANDmura and Leny.
- In St. Petersburg, behind the Vitebsk railway station, there are a number of parallel streets - Ruzovskaya, Mozhaiskaya, Vereiskaya, Podolskaya, Serpukhovskaya, Bronnitskaya and Bataysky lane. It is impossible to remember their order if you do not use the taxi driver's code phrase: "Timeve we canbut faithgo underscrap graydtsu brochildish balerins? "
And here are some more phrases invented by taxi drivers:- "Squirrel Will Just Dry Loaf" (Belcity, Budapeshtskaya, Booarrest, Etcazhskaya and FROMofiysk).
- Prospectuses - Science, North, Lunacharsky, Enlightenment, Suzdal gave birth to an unforgettable phrase: “On Northe Moonand Prosthen Susit was ".
- Prospectuses of Culture, Rudnev, Artists, Yesenin, Engels - "Every Innovator Wants to Experiment Daily".
- In order for children to be able to remember the sequence of Latin letters on the chessboard (ABCDEFGH), the phrase is used: "Artist Bimu Give a Compass, His Surname - Zhe-Ash".
- "Ivan gave birth to a girl, ordered to drag the diaper" phrase for memorizing Russian cases.
Another variant: "Ivan Rodionovich Give Your Pipe a Smoke". - Memory for the number "e" to the 15th decimal place (e \u003d 2.718281828459045 ...)
Two commas seven miles is not a hook (2,7) + two Leo Tolstoy (Year of birth of Tolstoy 1828) + rectangular isosceles (the angles of an isosceles right-angled triangle are 45, 90, 45). - "The gypsy stood on tiptoe and poked at the chicken: Chick!" phrase for memorizing words, where after "c" is written "s".
- And here is an old rhyme for memorizing where instead of "e" it was necessary to write "yat":
B (f) liy, b (f) dny, b (f) d b (f) c
Ub (e) sting b (e) denag in l (e) s,
L (e) shim by l (e) su he b (e) gal,
P (e) dkoy with xp (e) nom poob (e) gave ... - The average speed of the thermal motion of a particle v \u003d sqrt (3kT / m) is remembered as "three cats for meat" (m is the mass of a Brownian particle, v is its velocity, k is the Boltzmann constant, T is the temperature, sqrt is the square root).
- Phrase "One shaved Englishman chewed dates like carrots" helps astronomers memorize the spectral types of stars in order from hot to cold (O, B, A, F, G, K, M).
English version: "O Be A Fine Girl, Kiss Me"since then the classes R, N and S were added, then the phrase turned into "O Be A Fine Girl, Kiss Me Right Now ... Smack".
What mnemonic phrases do you know? Complement!
P.S. And finally, an old tale about party mnemonics:
Even during Soviet times, in one of the military schools, at lectures on the History of the CPSU, a lecturer colonel dictated a mnemonic rule for memorizing the composition of the first Marxist group in Russia: "Plekhanov, Ignatov, Zasulich, Deutsch, Axelrod - take the first letters of the surnames, add them up for life remember what happened. "
