The traditional colors of the rainbow, often remembered using the acronym ROYGBIV, represent the spectrum of visible light and include:
1. Red
2. Orange
3. Yellow
4. Green
5. Blue
6. Indigo
7. Violet
These colors form the classic seven-color rainbow typically observed after rain or mist, with red being the outermost and violet the innermost color. However, it's important to note that the rainbow is a continuous spectrum of colors, and different cultures and contexts may recognize variations in the number or interpretation of colors within the rainbow.
