Rainbow Colors: Why Don't You See All Colors In The Rainbow?

There are three main reasons why we don’t see all the colors in a rainbow:
1. The colors we see in a rainbow are spectral, which means they are also present in the visible spectrum.
2. Some colors, like pink and brown, are made when two different colors mix together, and the rainbow colors don’t mix.
3. Our eyes can only see a certain range of colors, so some colors, like those in the ultraviolet and infrared regions, are invisible to us.

Another interesting fact is that everyone will see slightly different shades of color when we look at the rainbow. It’s how our eyes look at it. Different sets of eyes mean different responses to colors.
