The middle color of a rainbow is green.
Rainbows are formed when light is refracted, or bent, and then reflected inside water droplets, resulting in a spectrum of colors. A typical rainbow displays seven distinct colors, which are red, orange, yellow, green, blue, indigo, and violet. These colors can be remembered using the acronym ROYGBIV.
In this sequence, green is located approximately in the center. If you consider the seven colors, green is the fourth color. This positioning in the spectrum is a key reason why green is often associated with growth, nature, and harmony. So next time you spot a rainbow, you can easily identify green as the middle color among its vibrant hues!
