The colors of the rainbow, in order from the top (or outside) to the bottom (or inside), are:
1. Red
2. Orange
3. Yellow
4. Green
5. Blue
6. Indigo
7. Violet
These colors are the visible spectrum of light as it is split by refraction, which is the bending of light as it passes from one medium to another, such as through a raindrop or a prism.
