The rainbow is one of the most amazing things in nature. It’s a beautiful sight to see, and it’s so unique because there are seven different colours that make it up. Each colour has its own special meaning and symbolism. In this blog post, we’ll take a look at the seven colours of the rainbow and what they mean.
Have you ever seen the seven colours of the rainbow? Most people see red, orange, yellow, green, blue, indigo, and violet. They are usually in that order. The colours are in a spectrum. Red is on one end and violet is on the other. Indigo is in the middle. Blue and green make up the two ends on either side of indigo. Yellow and orange are right next to each other near the red end of the spectrum. Violet is very different from red because it’s on the other end of the spectrum. It’s also very different from all of the other colours because it doesn’t have any close neighbours. Have you ever seen anything that has all seven colours? Some things have six out of seven. An example of this would be a rainbow.

How is Rainbow Created?
To create a rainbow, you need sunlight, a raindrop, and your eyes. Sunlight is composed of the seven colours of the rainbow: red, orange, yellow, green, blue, indigo and violet. When white light passes through a raindrop it splits up into all its different colours. It then forms a circular arc in the sky with its different coloured bands. Sunlight enters a raindrop. It separates into the spectrum of colours. The seven colours form the band of a rainbow!

Why Rainbow has 7 (Seven) Colours?
Rainbows are formed when sunlight falls on raindrops. The light enters the raindrop, which acts like a prism and separates it into its component colours of red, orange, yellow, green blue, indigo, and violet. All of these colours then spread out into their distinctive bands to create the rainbow effect.
