A rainbow typically displays a spectrum of colors, commonly referred to as the seven colors of the rainbow. These colors are:
1. Red
2. Orange
3. Yellow
4. Green
5. Blue
6. Indigo
7. Violet
The acronym "ROYGBIV" is often used to remember the sequence of colors in a rainbow, with each letter representing the first letter of each color: Red, Orange, Yellow, Green, Blue, Indigo, and Violet. However, it's important to note that a rainbow is a continuous spectrum of colors, and the transition between colors is gradual rather than distinct. Additionally, under certain conditions, rainbows may display additional colors or variations in hue.
