What is this violet colored spread in the sky? - Half moon in purple sky at sunset

Today on my way from Madison, WI, USA to Minneapolis, MN, USA on highway I94 I saw sky light up with violet color. Timestamp on my picture is at 6:48 PM. It's very strange. I do not think it was northern lights, too soon to hop on alien story. I know this could be due to some lights, but it was so bright and spread across such a large area, its stuck in my head. I am attaching pictures. Not very good quality as I was driving.

Let me know if you guys have any guesses. enter image description hereenter image description here

What does it mean when there is purple in the sky?

They say that the purple sky is an optical illusion caused by the way our eyes process colors. This happens when there is a lot of light pollution in the air from things like streetlights and car headlights; these lights can cause our eyes to \u201cadjust\u201d to see more blue and violet colors, making the sky look purple.

What causes a pink purple sky?

This can be in part, the optical illusion of the pink wavelengths lighting up the base of the cloud (due to the low angle of the sun's rays), and these pink clouds superimposed on a dark blue sky. The combination of pink and dark blue can make the sky appear a deep purple.

Why is the sky lilac?

Shorter wavelength colours like blue or indigo are easily scattered while oranges and reds can pass through. Combined with a usualy dark blue, this creates the warm pink and lilac glow - and is also why we sometimes see a red sky in the morning or evening.
