How many colours in rainbow?

There are many answers to this question. There’s the full answer, which is “seven”: red, orange, yellow, green, blue, indigo and violet. But there’s also the short answer: “five”. Having looked at lots of rainbow images on Wikipedia I think it would be fair to say that most people expect the rainbow to have five colours. The other two colours (red and violet) are often blended into one darker colour (magenta). This means that if you simply count how many colours there are in an image then you’ll get either four or six depending on whether or not you include magenta as a separate colour. To avoid arguments about what should be classed as a separate colour (and because I’ve only got Paint Shop Pro on this computer) I’m just going to look at images where each colour is clearly separated.

The short answer, then, is “five”. The long answer – which takes more words – is that the rainbow has seven colours but five of them (red, orange, yellow, green and blue) are clearly defined whereas indigo and violet are either blended into magenta or else hard to spot because they’re washed out by the sky’s glare.

How many colours in rainbow?

There are exactly seven distinct colours in a rainbow: red , orange , yellow , green , blue , indigo and violet . This fact was first proposed by Sir Isaac Newton in 1675. Considering that these seven colours only make up a small portion of the visible light spectrum, it’s amazing how vibrant and beautiful these seven colours are.

The correct answer is that there are ten colors in a rainbow: Red , orange, yellow, green, blue , indigo, violet , cyan (blue-green), magenta (red-purple) and yellow-green. While this list may be slightly different from your list of colors, they are all still very much real. Keep reading for more information! Scientists have discovered that the reason why rainbows appear to have fewer or more colors than expected is because water droplets act as natural prisms . This essentially works by refracting different wavelengths of light at different angles. These different wave lengths correspond to different colors that we see.

How to remember the colours of the rainbow

From a very early age, we’re taught how to remember the colours of the rainbow using what is known as a mnemonic.

This is a phrase that takes the first letter of each colour and makes up a new word which, in turn, creates a phrase that’s easy to remember.

One of the traditional mnemonics is Richard Of York Gave Battle In Vain, but it’s easy to make up one that’s relevant to you.
