I heard that the violet in rainbow is only created because the bottom blue coincides with another inner rainbow’s top red. I forgot where I heard it but it sounds logical.
Whenever I see the EM spectrum, it always goes from red to green to blue then to VIOLET which I don’t know how it got there. What bothers me more is how there’s an infraRED and then it goes ultraVIOLET.
I remember in preschool that red + blue = violet so where did the red from the violet part of the spectrum comes from?

Mixing light and mixing pigments do not have the same effect. Mixing red, yellow, and blue paints will get you a dark muddy mess. Mixing red, green, and blue light will get you white light. So the mixing of blue light from one rainbow and red from another is completely incorrect.
Visible light is just a very small portion of the electromagnetic spectrum. The different colors are simply different wavelengths. Just as your ears can only hear certain sound wavelengths (can’t hear ultra low sounds or ultra high sounds), your eyes can only detect a portion of the EM Spectrum.
