This is a good right answer, but some others in the last bread were also good.
However I take issue with the blue indigo thing.
I speak Russian and Ukrainian a lot
In those languages there are two colors that we call blue in English
Skyblue, and navyblue
In the image
Red Orange Yellow Green Skyblue Navyblue Purple
Same as a real rainbow.
The problem is that indigo, the color of the dye made from the indigo plant, was a bit darker than common navy blue. It was the color of brand new blue jeans but that is no longer true since designers are messing with the colors.
The point is that Indigo is a darker shade of dark blue than royal blue. But most people do not use the name indigo any more because it is no longer common to see products dyed with pure indigo dye.
It is no longer special
In any case, there are no colors at all in a rainbow. They are in your head. In your mind. In someplaces in Africa those girls are
Red Orange Yellow Light blue, Medium Blue, Dark blue, Purple.
Yes, I said light blue, like grass or tree leaves.
And in Hungary one color is missing at the beginning. There should be two colors before Orange. Red and Crimson.
Oh, and some people can see ultraviolet after the purple. They describe it as a kind of watery pinkish purple. By watery I mean diluted or translucent.
