Same as homo's hijacked God Covenant, the rainbow and everything else that Satan tries to subvert from God.
Are those colors of the rainbow?
They sure are. They're not usually listed in the spectrum colors like indigo (dark blue) is, but every shade of every color we can see absolutely is present within the rainbow.
Just think about all the colors birds can see and we can’t? Are those rainbow too? 😋
For humans visible light is a tiny part of the electromagnetic spectrum. What a creature sees when light is diffracted is the gradient of that creature's visible spectrum. I'm not sure where the bird's visible colors begin and end, but I do know that the mantis shrimp sees much more of the EM spectrum than humans do.
