Something I find unsettling about my vision
I grew up in southern California but now live in a mountain state. Whenever I go back to visit, I've noticed my perception of anything more than 20 feet away feels off, like there's a filter being applied to my vision. Colors are a bit washed out and slightly more red than they should be, while shadows are darker. Another way to think of it is how you can tell what decade media was filmed in based on the color technology, it feels like I'm switching between two decades.
At first I thought this was a pollution thing, but then I visited Hawaii and remote parts of coastal Oregon and noticed the same thing was true there as well. Whenever I've talked to others traveling with me about this, no one has said they have the same thing happen, they all perceive the colors as normal. Searching online didn't reveal anything. I feel a bit crazy because the change is fairly jarring and disturbing to me. The only thing I can think is it must relate to atmospheric differences at sea level versus higher elevations, but I'd really like to know more about what I'm experiencing.
A few notes about me: I am male, so something like tetrachromacy is extremely unlikely. I do not have color blindness and my vision has always been exceptional, with 20/10 vision. I doubt it's relevant, but I do have central heterochromia (blue outer iris with gold inner ring around the pupil).
