"The rainbow shows us all the individual wavelengths of visible light in order, from the longer wavelengths (red) to the shortest that we can see (violet). These are the purest colors – each one has just a single type of light wave associated with it. But reality often isn’t so simple.
I’ve got a rose bush with bright pink roses outside my window, and I’m looking at it as I type this. The problem that my brain has is that the information from my eyes says that there is both red and violet light coming from the same rose.
A mixture of light from different regions of the rainbow is coming from the same place. What my brain needs to do is to interpret that information to distinguish it from objects that are just reflecting red light and those that are just reflecting violet. So it makes the interpretation that the rose is pink, a combination of red and violet.
We need to understand mixtures of the rainbow colors quickly,

We need to understand mixtures of the rainbow colors quickly,
so
our brain gives us a single color for each mixture. This is what gives us the huge richness of color in our world when there’s only the simple spectrum of the rainbow as the raw material. It’s all about combinations, and we see each different combination of lightwaves as a different single color.
The reason that pink isn’t in the rainbow is that the rainbow shows colors in order. There’s nowhere in a rainbow where red and violet overlap, because they’re at opposite ends of the spectrum. So although pink is a real color, it doesn’t have a place in the rainbow." BBC
The complexity of eye/color coordination, brain complexity for instantaneous interpretation, the organization of color and the rainbow itself-------as the Psalmist said- When I consider....the work of thy fingers, ....What is man, that thou art mindful of him? Psalm 8:3,4
