The center of a rainbow is typically a shade of green. A rainbow is a meteorological phenomenon formed by the refraction, dispersion, and reflection of sunlight in water droplets, resulting in a spectrum of light appearing in the sky. The colors of a rainbow, listed from the outer edge to the inner, are red, orange, yellow, green, blue, indigo, and violet. The green band often appears closer to the center, leading to its perception as a central color. However, the arrangement of colors can vary slightly based on the observer's perspective and the specific conditions of formation.
