Nature is the most beautiful, giving, and mesmerizing part of the universe. The most splendid creation that occurs in nature is a Rainbow. A Rainbow is one of the most beautiful naturally occurring phenomena in nature. In the early times, rainbows were part of many mythological tales; it was considered a positive omen occurring in nature. Some scientists also believe that rainbows exist on Titan, the moon of Saturn.
When the monsoon season strikes, we have all encountered a Rainbow at least once. Rainbows comprise many colors like red, yellow, and blue, but some people get confused about how many colors are precisely there. Are there many colors? Is Rainbow a Single color? So what exactly are the colors of a rainbow? Before finding out that let’s see how a rainbow occurs.
How and When Does a Rainbow Occur?
Water is denser than air when light passes from air to the raindrops at an angle, the light slows down, and refraction of light occurs, resulting in a Rainbow. Rainbows can never be found at a fixed place; when sunlight falls on raindrops and reflections, refraction of light happens. Greek Philosopher Aristotle first mentioned the Rainbow in 350 BC, but Isaac Newton gave the Rainbow a scientific explanation. The reflection of light in water droplets results in a spectrum of light, creating a series of concentric colors in the shape of an arc. A rainbow is always on the opposite side of the sun.
Structure of a Rainbow?
In a Rainbow, The outer arc starts with red and ends with violet on the inner side. Rainbows can be found in fog, sea spray, and waterfalls as well. Rainbows do occur in a full circle, but no one can see a full circle rainbow unless they are on an aircraft, which is rare.

More than ten types of Rainbows arise worldwide, and the color depends upon the place weather they may occur in. The traditional primary Rainbow that occurs frequently consists of 7 colors. These seven colors are-
Rainbows are frequently occurring in nature, but some people still don’t know a lot about rainbows. To remember the classic color sequence, we were taught many abbreviations, like the first letter of each color, for example-VIBGYOR or ROYGBIV. It would be much easier to make your abbreviation for you to learn quickly.
