When sunlight shines through raindrops, a beautiful arc of color can appear in the sky!
A rainbow has seven main colors, appearing when sunlight passes through raindrops and splits into red, orange, yellow, green, blue, indigo, and violet, always in that order.
Three colors and twelve colors are both wrong counts, the classic rainbow is described using exactly seven distinct bands.
Rainbows appear opposite the Sun in the sky, so you need the Sun behind you and rain or mist ahead, and no two people ever see the exact same rainbow, since it forms at a slightly different angle for each viewer.
