For as long as the sun is behind you in a clear sky and
the sky in front of you has water droplets in it.
All colors visible to the human eye are in the rainbow. They have no specific meaning.
There are conditions that permit viewing two rainbows at once. The primary rainbow is as one might expect, but a secondary rainbow is visible above the first one. There is a nice picture and a description posted at Wikipedia, and a link is included.
A rainbow is composed of light. Light does not reflect light.
Red is the color that appears first in a rainbow, on the outermost arc. It has the longest wavelength of all the colors in the visible light spectrum.
The visible light spectrum is the part of the spectrum that can be separated into rainbow-like colors. This range of wavelengths extends from about 400 nanometers (violet) to 700 nanometers (red).
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 visible spectrum
Visible light is the electromagnetic wave seen in a rainbow. This light is refracted, reflected, and dispersed by water droplets in the atmosphere to create the colors we see in a rainbow.
All colors visible to the human eye are in the rainbow. They have no specific meaning.
A partial rainbow is called an arc or a fragment of a rainbow. It occurs when only a portion of the full circle of a rainbow is visible in the sky.

"rainbow"
The fastest color in the rainbow is blue, as it has the shortest wavelength among the visible colors of the spectrum.
There are an infinite number of colors of visible light,and ALL of them are present in a rainbow.
The longest visible wavelengths are thoseat the red end of the spectrum (rainbow).
