No it does not. The rainbow has all wavelength within the visible spectrum. But not all colors. And yes, color is based on perception.

Yoy can filter out frequencies in the rainbow spectra in a way that it looks like any color..

You can do that with white light, but not in the rainbow, because the wavelengths are spatially already separated. So you would also have to combine them again.
