I asked him “what color were the clouds back then?” and he said they were white. I asked him what happens if I take an orange light and light up something that’s white with it. He ignored me. He went on about how everyone in his age group remembers the Sun being orange, and by me questioning him, I’m calling him and all his peers liars and I’m stupid because I’m younger than him and vaccinated.
A simple google will tell anyone the following
He could be a liar, I dunno, but he is definitely a doodoo head

Edit: your friend is almost certainly unconsciously mistaking the shift to LED bulbs as the “deyellowing” of society
We perceive the sun as white. That’s a fairly important distinction.
The reason we perceive the sun as white is surely because the sun has output basically the same spectrum as long as humanity (and a great deal of humanity’s precursors) has existed. We evolved with our eyes considering the spectrum the sun kicks out as fully white light, comprised of the sum total of electromagnetic frequencies we’re able to receive with our eyeballs.
There is no such thing as objective color of any light. Our understanding of color is completely based on our perception of it. If the sun’s peak output were in the 590–625nm range (what we currently perceive as orange) for all that time rather than in the green part of the spectrum it is in reality (500–565nm), we undoubtedly would have evolved to see that particular spectrum combination as white light instead.
All of the above notwithstanding, if the spectrum output of the sun changed overnight like OP’s idiot friend is suggesting, it would be immediately apparent to everyone who isn’t literally blind.
One point on perception - doesn’t the sun appear somewhat yellow because the blue light has a stronger tendency to scatter, meaning that the roughly white light of the sun is less blue, with all the blue color of the sky being taken away from the color of the sun?
More or less, yes. That’s also why it appears more red/orange as it gets closer to the horizon from your perspective, since at that oblique angle the light has to pass through more of the atmosphere to get to you and more of it gets scattered or absorbed by particulates in the air.
The sun is actually green and our brains autocorrect it to white??? What the fuck
Last time I checked, human output was brown.
And if it’s not someone should check in with humanities veterinarian…
Ok. Devils advocate here. If it did change, and did it gradually, would we notice? And if it changed suddenly wouldn’t we adjust and soon see things as we always have?
The question is how gradually. Over the span of 10,000 years, probably not. Over the span of a month, absolutely. Remember that the hue of sunlight already changes significantly throughout the day based mostly on the sun’s proximity to the horizon (and thus how much thickness of crap in the atmosphere it has to plow through to get to your location) and we can definitely detect that easily.
Where is the ambient horizon lighting coming from in the right-side of the picture?
From light pollution. Or it’s just early morning in there.
I’m pretty sure it’s cgi upon inspection lol
