What types of colors does a single raindrop illuminated by sunshine disperses?

A single raindrop illuminated by sunshine disperses light into a spectrum of colors, primarily due to the phenomenon of refraction, reflection, and dispersion. This process separates white light into its component colors, typically forming a visible spectrum that includes red, orange, yellow, green, blue, indigo, and violet. The result can be seen as a miniature rainbow, with the arrangement of colors depending on the angle of light and the observer's position.
