A rainbow is formed when sunlight is refracted, or bent, by raindrops in the atmosphere. This refraction separates the sunlight into its component colors, creating the colorful arc of a rainbow. The colors that make up a rainbow are red, orange, yellow, green, blue, indigo, and violet.
The reason why a rainbow doesn't have a black stripe is that black is not a color in the visible spectrum of light. Black is the absence or the absorption of all colors. In other words, it's what we perceive when there is no light or when all light is absorbed.
Since a rainbow specifically forms through the refraction and dispersion of sunlight, which consists of various colors, black does not come into play. A rainbow can only display the colors that are present in sunlight, and black is not one of them.
