The winter after I bought my first ARM based (or Apple Silicon powered) MacBook I noticed that often about half an hour after sunset, within 10 seconds all the screens (the built-in and external ones) would get a red teint on them.
[Wayback/Archive] MacBook Red Screen Issue – SimplyMac was the very first search result, and mentioned this:
Adjusting Night Shift and True Tone
Night Shift and True Tone features can affect the color temperature of your display. Night Shift reduces blue light in the evenings, which can make the screen appear warmer. True Tone adjusts the display’s color temperature to match the ambient lighting. If these settings are misconfigured, they could contribute to the red screen issue. Check your Night Shift and True Tone settings in the Displays section of System Preferences to ensure they’re set correctly or turned off.
I had to turn off both Night Shift and True Tone to get rid of this artefact, though for some people that didn’t solve the issue: [Wayback/Archive] Screen has red tint at night (True Tone and Night Shift are Off) – Apple Community.
I fully agree with [Wayback/Archive] Am I the only one who prefers True Tone?* : macbookpro
The only thing I like about true tone is how great it looks when I turn it off.

I was soooo disappointed with how crap the display was on my M1 Max that I thought about selling it as soon as I got it. Decided to play around with display settings and found True Tone. Turned it off and felt immediate relief. That’s how bad I think True Tone is. Absolutely flabbergasted that Mac’s come out the box with it enabled.
My 2015 MBP screen looks better to me than a M series screen with True Tone on.
