Since ancient times, the rainbow was considered a symbol of extraordinary luck and luck. A bright, glowing multicolored arc in the sky pleased the eyes of everyone who saw it, certainly improving the mood and letting for a moment forget about the problems and worries.
The old people said: "If the rainbow flares up in the sky from the very morning - it means everything will be easy and happy."Some people still even think of themselves when they see this beautiful phenomenon of nature. It is believed that, how many colors a rainbow can discern a man, so many desires he can guess.
Therefore, today we will talk with you about the order in which colors of the rainbow are and how many of them.

Rainbow: what is it simple?you
Rainbow - a natural optical phenomenon that occurs not only in the sky. Its essence is the refraction of light and the appearance of flowers. Physicists have proved that light has a certain range of shades, and the rainbow visually demonstrates this.
It arises from the refraction of light in the smallest droplets of mist or rain water that soar in the atmosphere. Light differs in different ways in droplets of water, hence different shades appear.
Where it is observed
As it turns out the rainbow can be seen not only in the sky. You can see a small rainbow if you sit next to a fountain and catch the refraction of light near a stream of water. You can see it on a white sheet of paper when you write with a transparent pen on a sunny day. Also, a rainbow can be seen through a prism, if this prism is brought to the sun's rays or to a conventional electric bulb.
But more often, we see a rainbow in the sky.
How many colors in the rainbow: the basic colors in order
Scientifically proven that any rainbow has seven colors. It is:
- red;
- orange;
- yellow;
- green;
- blue;
- blue;
- purple.
In antiquity, there were not so many precise optical instruments to carefully consider how many colors the rainbow has. And the human eye can not always accurately determine the color gamut.
Aristotle, for example, distinguished only three primary colors - red, yellow and green. But in Japanese culture there is no traditional green color, so the people of the Land of the Rising Sun believe that there are only six colors in the rainbow.
The great physicist and mathematician Isaac Newton devoted much time to studying the refraction of light and came to the conclusion that there are five colors in the rainbow. Then he considered the sixth - orange. This number - six - seemed to him imperfect for describing the phenomena of nature, so he decided to add a blue color to the rainbow, which he called "indigo."
We have 7 colors of the rainbow, they have 6
If you think that after the proven fact of scientists, how many colors in the rainbow, all people on the planet agreed with this statement, you are deeply mistaken.
In China, for some reason, believe that the colors in the rainbow are five - just as many as the elements on the planet. Until now, in Germany, America, England, France and a number of other countries, children are told that the rainbow consists of six colors.
Why does this happen? The fact is that blue and blue colors are very similar to each other, they are only distinguishable by the degree of depth. In addition, in a number of languages, "blue" and "blue" are called the same. In English there is only one common word for describing these colors. Therefore, until now, there is such confusion, how many colors in the rainbow.
Remember the basic colors in order simply
The order of colors in the rainbow is always unchanged, no matter what part of the world we observe it and at what time of day, large or small, stood for a long time in the sky or flared up and went out in a few seconds.
The first color is red, which gradually becomes lighter and turns into orange. In turn, the orange becomes even lighter and turns into yellow. The yellow color gradually turns green, then a blue appears, which turns into a juicy blue, and the last, final color of the rainbow spectrum is purple.
Remember the order of colors in the rainbow is quite simple. You only need to learn one mnemonic phrase - and you can easily name what flowers in the rainbow, without hesitation.
So, learn this sentence: " Every Hunter Wants to Know Where Sid Pheasant ".Simply and easily. And now you only need to take the first letter of each word and name the color of the rainbow:
- each - red;
- hunter - orange;
- wishes - yellow;
- know - green;
- where - blue;
- sits - blue;
- pheasant - purple.
It is this phrase about the hunter and the sitting pheasant that has taken root in the Russian-speaking culture. Although there are several more successful proposals that allow you to remember the rainbow spectrum. For example: " Once Upon a Time Once Jean Zvonar the City Broke the Flashlight ".There were also more modern interpretations: " Every Designer Wishes to Know Where To Download Photoshop ".
Well, it's already, as they say, to choose your taste, how to remember the arrangement of colors in the rainbow.
Cold or warm
Rainbow on the horizon always seems bright, cheerful, lively and very warm. It shines and sparkles and it seems that everything consists of fiery flowers. But, nevertheless, there are also cold tones in it.
Let's figure out how many cool colors in the rainbow.
Everything related to blue color refers to cold tones. Thus, in the rainbow, three cool colors - blue, blue. Green is neutral( like white).But purple, which has shades of purple, is not referred to either warm or cold tones, it is transitional.
Accordingly, and the warm colors of the rainbow are three: red, orange and yellow.
This palette, which divides colors into warm and cold, is used by artists and painters. There are even a few color circles that divide the solar spectrum into warm, cold and intermediate shades.
A colorful arc in the sky is always against the sun
The rainbow always appears on the opposite side of the sun. So if you look at it, the sun will always shine from behind. Most often the rainbow appears in the morning or evening, and this also has a completely reasonable explanation from the point of view of physics.
When the sun is on the horizon, the rainbow is the fullest and largest. The higher the sun rises, the less the semicircle becomes. And when the luminary rises to a height of 43 degrees with respect to the horizon, it is already impossible to consider the rainbow. Because the angle for refraction of light is inappropriate.
The red color of the rainbow is always located in the outer part of the arc, and the violet in the inner part. But! Very often there is a double rainbow when there are two arcs in the sky. So, in the second rainbow, colors have the opposite layout.
By the way, to see two rainbows is considered an even greater success than one.
Rainbow: interesting facts
The number of colors in the rainbow always remains unchanged, but the ideas about this beautiful optical phenomenon in people have changed over time. Ancient tribes, for example, divided the rainbow into two colors - dark and light.
The rainbow can be seen not only in the sun's rays, but also after the darkness comes. Then the sun's rays begin to reflect from the moon, and a rainbow can arise.
The rainbow does not freeze in place, but two people who are in different parts of the city will see it in a completely different way. One will feel that it is hanging over the river, and the other - that it is located directly above the new buildings. That's why when you take pictures of a rainbow in the same city at the same time, you get completely different pictures.
Not all people can see all seven colors of the rainbow. It depends how sharp your vision is. Some may notice in the rainbow shades of pink, peach, light green. And they do not invent. After all, seven colors are the main classical colors. And the shades in the rainbow are really great, and some can not be caught with the human eye.
Rainbow can disappear if you wear glasses with polaroid glasses. The coverage of these glasses is located so that the light is refracted vertically and the person simply does not see what the others see.
