I snapped a picture of a beautiful double rainbow after a short rainfall. I didn’t notice that the top rainbow was inverted color wise from the traditional order. Can someone please explain why the top rainbow is inverted please?

It’s because the specific prismatic effect you’re seeing at that moment happens to peak at or very near to the top of visible light. After the prism peaks, the wavelengths of the light go back down through the visible spectrum so the parts you can see begin again where you stopped being able to see them (ultraviolet) and descends through the visible spectrum then goes infrared and disappears again.
