I'm having trouble understanding the Belt of Venus one. Isn't purple expected to be there per ROYGBIV? Also the second image looks orange to me, not purple.
> It is a pinkish glow that surrounds the observer
This also makes no sense to me, or else maybe observer is jargon? But there's no hyperlink... The photographer certainly doesn't seem to be surrounded by a pinkish glow.
Is it just a name for the purple part of the spectrum?

I do not understand the Physics of the phenomenon very well, but I would expect the high frequency wavelengths (for example, purple) to be scattered away.
"Surround" does not describe the phenomenon of Belt of Venus adequately. Think of it like a horizontal band wrapped around the dome of the sky, slightly above the horizon, and prominent towards the West, fading towards the East.
