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.
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.
