A rainbow is formed when sunlight is refracted, or bent, by water droplets in the air, which causes the different colors of light to separate and form a circular arc in the sky. The colors we see in a rainbow are red, orange, yellow, green, blue, indigo, and violet.
Black is not a color of light but rather the absence of light. It is formed when all colors of light are absorbed, and no light is reflected back. Since a rainbow is created by the dispersion of light, there is no way for black to be a part of it.
Therefore, a rainbow will never have a black stripe because black is not a component of the visible spectrum of light that creates a rainbow.
