This is the BlackBerry building in Irvine, more formally known as 400 Spectrum Center. Along with its twin it's the tallest building in Orange County, topping out at a breathtaking 323 feet. That's a full 12% of the height of the Burj Khalifa in Dubai, the world's tallest building!
It's also clad in some kind of special glass that makes it take on the color of its surroundings. It doesn't disappear or anything, but it often blends in surprisingly well. It's hard to get a good picture of it thanks to the tight surroundings, but a few days ago I had the rare pleasure of being a passenger while Marian drove and I got this shot out the window of her car while we were tooling home on the 405. It was a very hazy day, and while the building is obviously quite visible, you can see that it's also taken on some of the day's haziness.

Beautifully eerie - I think!
Bird collisions? (yes, I almost said collusions)
The most wonderful thing about your locatio pictures is they remind why I never want to live in California.
Kevin's photos do just the opposite for me. I've spent a considerable amount of time in California (including months and months of a pandemic-related , stranding last year) but almost all of it in the Bay Area. But KD's got me wanting to transfer my West Coast presence to SoCal.
(Although, sure, in this particular case I can see your point, as smog's not a very pleasant thing).
This isn't smog, it's haze.
Got it.
My favorite season is winter so....
I do find the northern part of the state pretty.
Kevin, you would like the Hancock Tower in Boston - one of my favorite buildings. And Trinity Church at its foot is pretty special, too.

If I were to guess, they selected a near-clear glass with a low Solar Heat Gain Coefficient. All of the means of achieving that low SHGC -- whether fritted glass, film, or coating -- would have provided a hazy reflection, allowing the building's facade to blend into the background of a hazy sky.
