It's not possible to give a complete answer to that question, for two main reasons:
1). The human eye is capable of differentiating about 10 million colors,
and they're ALL in the rainbow.
2). Most of them haven't even been named.
All colors visible to the human eye are in the rainbow. They have no specific meaning.
The visible spectrum
Visible light.
Visible Light Spectrum.
Visible light includes all the colors of the rainbow. The different colors are the result of different wavelengths.
Red is the lowest. From there, frequencies increase, in the order of the colors of the rainbow, until you reach the highest visible frequency at violet.
The colors of the rainbow in order are...RedOrangeYellowGreenBluePurple
You see all the colors in a rainbow.
A rainbow? I mean you are seeing the entire visible spectrum... Rainbow isn't the most scientific word but it's something...rainbow is refracted light so yea final answer... Rainbow
water separate white light into visible light
The rainbow offers a representation of the visible spectrum of light for human eyes, this is a wavelength of 400nm. The mnemonic device "Roy G. Biv" is easily remembered to dictate the order of the colors: red, orange, yellow, green, blue, indigo and violet. Any other visible colors are a derivation of these.
Red, Orange, Yellow, Green, Blue, Indigo and Violet are the colours of a rainbow visible to the human eye. These are the colours as originally stated by Newton. Infrared and ultraviolet can also appear at either end of a rainbow but these colours aren't visible to the human eye.
