Rainbow Colours- What is 7 Rainbow Colours in Order?

Rainbow Colours Names

A Rainbow is a multicolor curve that occurs in the sky after rainfall. It is a result of reflection and refraction between sunlight and water drops. When the sunlight passes through the water drops or the rain, the light gets refracted and the droplets reflect it from the surface, as a result, it gets refracted at different angles. The different colours we see in a rainbow colours is due to different wavelengths of light, as the light gets refracted in many angles, all the angles form different wavelength resulting in the distribution of different colors.

Rainbow Colours Name

It is derived from the word ‘Renboga’ which is an old English word. It is made of two words ‘regn’ which means rain and ‘Boga’ which means curve, bent, or arched.

Why rainbows Colours are so fascinating?

Rainbows are very special and attractive. It is a wonderful creation of nature that fascinates people. All age groups, kids, youngsters, elderly people, everybody loves to see a rainbow after a rainy day. It is all about the beauty and rareness of the rainbow that makes it more special. People find it lucky if they get to see a rainbow. There is also a rainbow thing called double rainbow which is very rare and it is said that there are two rainbows in the sky at the same time. Isn’t it fascinating!

Rainbow Colours Name Order in English

We all know, there are seven colors in the rainbow, and we find it difficult to remember all the seven color names. There are a few short forms you can use to remember like VIBGYOR, which is one of the most used ones. Some people also use ROYGBIV, just the reverse of VIBGYOR.

The seven Rainbow colours are-

  1. Violet
  2. Indigo
  3. Blue
  4. Green
  5. Yellow
  6. Orange
  7. Red

You must be wondering why we do not see all these colors at once or why we do not see all the seven colors of the rainbow?

We do not see all the seven colors at once because we see the rainbow from different angles and it is not possible that the light gets reflected in that particular angle. As mentioned above, the wavelength of the light reflects the color and the wavelength depends on angle. Therefore, we all see a different rainbow from our point of view because it is from different angles.

Rainbow colours- Wavelenght

Wavelength is the distance from one crest to another or one trough to another trough of a magnetic wave or electromagnetic wave or sound wave.

Different colors have a different wavelength, all the colors in a rainbow have different wavelengths.

  • Violet: 380–450 nm
  • Blue: 450–495 nm.
  • Green: 495–570 nm.
  • Yellow: 570–590 nm.
  • Orange: 590–620 nm.
  • Red: 620–750 nm

Here, violet has the lowest wavelength and red has the highest wavelength, which means violet has the highest frequency, hence higher energy, and red has the lowest frequency, hence low energy. This is because the wavelength is inversely proportional to frequency. Indigo does not have any wavelength.

How many Colours in Rainbow?

Rainbow not only increases the curiosity of people now but for many and many years rainbow has been a topic of investigation for scientists. People were always curious about the mystery of the rainbow with many questions like, from where does the rainbow arise, where does it vanish after some time, why we see colors, why it comes after rain? Etc.

These questions were slowly and steadily researched, studied, and experiments and now people get to know more about the rainbow. It is all about the science behind the creation of the rainbow. From all the researchers and scientists, Issac Newton was the first scientist who understood and put light on the rainbow theory. He did this by experimenting several times, his main objective experiment was to pass white light through a clear prism, and then when the white light reflected and got refracted again by the surface of the prism, there were several colors from which he named the most prominent seven colors of the rainbow.

Seven Rainbow Colours

Rainbows are one of the most beautiful and fascinating things we see as a child and it stays with us forever, even if we know why it is created and what is their origin, a child in our heart will always try to find the different colors and the end of the rainbow. There are many things we still do not know about the rainbow, and there are many people who are still researching and experimenting to get a new turn after Newton in the rainbow theory.

Rainbow Colours- FAQ’s

  1. What is the shape of the rainbow?
    A rainbow is a circle in shape but from the ground, we can see a small part of it. If you are lucky enough you can see a full rainbow from an airplane.


  1. Does a rainbow exists?
    A real rainbow does not exist. When you see a rainbow, it is just an optical illusion, created by the reflection and refraction of waterdrops and colors.


  1. Is it possible to see all the seven colors of the rainbow together?
    No, you can not see all the seven colors of the rainbow at once because all the different angles produce different wavelengths which distribute different colors in each angle. So, it is not possible to be present in all the angles.


  1. Rainbows are man-made?
    No, rainbows are completely a natural phenomenon that is based mostly on science. You can make artificial rainbows bypassing using the same process in which a rainbow is made. You just have to get a set up for refracting and reflecting the light from water drops.


  1. Will the colors of the rainbow change?
    There are more than seven colors in a rainbow, According to Newton’s research, he only established seven colors because he wanted them to be similar to the seven musical notes. Since the light gets refracted in many angles, there are many wavelengths producing different colors.
