Almost everybody has seen a rainbow, one of the most beautiful natural marvels in our world. However, even though you have seen a rainbow, can you name each of the colors in order? In this article, we will be discussing what makes a rainbow and what are the colors of the rainbow. By the end, you will never be able to forget the colors of the rainbow.

 

 

What Is a Rainbow?

A rainbow may be a little more complex than a simple colorful arc. The first person or philosopher to describe light reflections and refraction in the 17th century was René Descartes.  Another famous scientist, Sir Isaac Newton, also contributed to this research with his glass prism experiment, which explained the breakdown of white light. When white light moves through a prism, the light refracts and produces various colors. This proved white light is composed of a vast spectrum of colors.

What Is a Rainbow Made from

These colors are visible to the naked eye and are part of what is known as the visible light spectrum. All colors have wavelengths, which can be measured in nanometers, for example, violet has a short wavelength of 380 nanometers. On the other hand, you have red, which has a long wavelength of 700 nanometers. When these colors pass through the prism, they will bend or refract at different angles, which is what causes the rainbow of colors visible to the eye. So, why does a rainbow have only seven colors? These colors form a visual spectrum, meaning each color blends into the next so there are no actual distinct colors. However, to make it easier to discuss the matter, Newton originally divided the spectrum into five colors. Since he was a fan of Pythagoras, who considered there to be a connection between music and color, he changed it to seven colors to coincide with the number of musical notes. This was a simple way to explain colors, however, there are not only seven colors. In fact, there may be more than one million colors, we simply just cannot see these other colors.

So, what is a rainbow? The rainbow you see in the sky is formed when sunlight passes through droplets of water, the light is refracted and reflected, thus creating the rainbow colors. For us to be able to see a rainbow, the angle at which light is refracted is 42 degrees.

Therefore, sunny, and rainy days are best to see a rainbow. The sun must also not be obscured by mountains or dark clouds. Depending on the weather conditions, a rainbow can last about an hour, however, there has been a record of a rainbow that lasted several hours in the city of Sheffield in England. Fun fact, the English name “rainbow” comes from an old English word known as renboga. This word was obtained from two words, one regn, which means “rain”, and boga, which means “arched”. Rainbows can even occur at night, particularly when it is a full moon. This follows the same process as the sunlight is reflected off the moon and hits droplets of water to form a moonbow. You can also have multiple rainbows, for example, a double rainbow, which is where the light is reflected twice within a droplet of water.

When this occurs, you will see a faint second rainbow just above the main one. You can also get tertiary as well as quadruple rainbows. Rainbows can also form by waterfalls, water fountains, and simply watering the garden so it does not always have to be raining. Rainbows can also come in a monochrome shade. This occurs at sunset or when the sun rises, where the colors like green and blue that have shorter wavelengths are scattered. This usually leaves a monochromatic red rainbow.

Fun fact, because of the horizon, when you view a rainbow from the ground, you can only see an arc. However, if you are flying in an airplane over the rainbow, you might get to see a complete circle rainbow, which is also known as a “glory” rainbow. A rainbow is an optical illusion and has no physical appearance, so you cannot touch it and is the reason why you cannot see the end of the arch and are never able to reach the end of the rainbow.

 

Colors of the Rainbow

Now that we have discussed what makes a rainbow, let us discuss further the colors of the rainbow. These are the rainbow colors in order, the red on top, moving to the bottom of the rainbow. One of the easiest ways you can remember these rainbow colors in order is to create a mnemonic system. This means forming a pattern of letters, for example, take the first letter of each color to form ROYGBIV. Most of us have learned that there are seven colors in the rainbow, which include the following official colors.

  • Red
  • Orange
  • Yellow
  • Green
  • Blue
  • Indigo
  • Violet

Colors of the Rainbow

Many get confused about indigo when comparing it to violet and blue. Indigo can be seen as a color midway between blue and violet. Some view this color as dark blue, while many other people view it as purple. However, purple is a blending of blue and red light, and these colors are too far from each other to overlap. Also, something to consider is that scholars believe that what was blue in Newton’s time, is now considered cyan, and what would be considered indigo in Newton’s time is now blue.  So, even though the visible light spectrum does not change, the way we perceive it seems to change.

 

 

Rainbow Colors In Order

Let us now take a closer look at all the rainbow colors in order. All colors have meaning and symbolism, and a rainbow plays an important role in certain religions and cultures. For example, the rainbow was a symbol to Noah in Bible times that God would not send floods to destroy the earth again. Certain cultures also have their beliefs about rainbows. Native Americans and Hawaiians believe it is a bridge that is a way to the afterlife. The Romans and Greeks believed a rainbow was a path for the gods. Most of us know about the pot of gold at the end of the rainbow, which is a sign of luck and is believed by some in places like Ireland. Colors are also said to affect things like our mood and health. What is the first color of the rainbow?
