Which is the last colour in a rainbow?

Paul Steadman, As you are aware of the ROYGBIV mnemonic I don’t see your issue.

in our school we have learned it VIBGYOR.

Paul Steadman, That's confusing too. Green is the middle color.

I found this question rather strange. This, at least to me, means nothing unless you use the ROYGBIV mnemonic. Perhaps a better question would be "which of the following colours is closest to the centre of a rainbow?"

I use ROYGBIV

I like that color violet. it comes with purple and blue together.
