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
purple or violet is the last of the visible light colors. purple
The most innermost color of the rainbow is violet. In the visible spectrum, the colors of the rainbow are arranged in order from red on the outside to violet on the inside. Violet has the shortest wavelength of visible light, which is why it appears at the innermost edge of the rainbow arc.

Visible Light Spectrum.
The rainbow colors are red, orange, yellow, green, blue, indigo and violet.
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
The colors of the rainbow are found in the visible light portion of the electromagnetic spectrum, which ranges from approximately 380 nanometers (violet) to about 750 nanometers (red). The visible spectrum includes the colors red, orange, yellow, green, blue, indigo, and violet, often represented in that order. These colors correspond to different wavelengths of light that can be seen by the human eye.
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.
There are an infinite number of colors of visible light,and ALL of them are present in a rainbow.
