For what it’s worth…
I first noticed this strange color pulsing only a few years ago, with the naked eye. Also, with low quality astronomical binoculars.
The ‘twinkle’ i had heard of as a kid, never really seen until i was in my fourties. According to a simple rationale, the starlight coming through near the horizon and passing through many hundreds of miles of atmospheric distortion, vs starlight passing through much less directly overhead. World full of so many lies, have no idea where to start anew.
