How many colors does a rainbow really have?

While we often talk about these seven colors, a rainbow actually contains many more.

The colors blend into one another, creating countless shades.

When light passes through water droplets, it refracts, bending and creating a full spectrum of colors.

In reality, there are millions of colors that the human eye can see.

The seven colors are just the most visible ones that we can easily identify.

Many people do not name or recognize the colors in a rainbow in everyday life.

A rainbow has seven main colors: red, orange, yellow, green, blue, indigo, and violet.

However, it also includes over a million other colors, some of which we cannot see with our eyes, like infrared and ultraviolet.

How do rainbows form?

To understand rainbows better, let’s look at how they form.

After a rain shower, the sun shines on the droplets of water left in the air.

When sunlight hits a droplet, it slows down and bends. This bending of light is called refraction.

As the light continues through the droplet, it reflects off the inside surface and bends again when it exits.

This process splits the light into its different colors.

Each color bends at a different angle, so we see them spread out in a circle.

If you were to see a rainbow from above, it would appear as a full circle.

However, from the ground, we only see the top half because the horizon hides the bottom part.
