Why are the people in the background changing color also?
Is this enhanced version of the video?
I looked this up online; and the trick is using a thermo-sensitive paint
where it becomes "translucent" with temperature change,
and reveals different colors underneath.
Here's another example of how the temperature change
reveals whatever is painted underneath (where it's just
the top layer that changes from opaque to translucent):
There is only 1 Bugatti Gran Turismo on earth, It was originally purchased by some Saudi prince in a secret auction. It was kind of a shady deal because they Prince who bought it wasnt a long time Bugatti customer. The auction was supposed to be reserved for their top customers, but this guy got in the auction because he knew someone who worked for the auction company that was handling the auction independently for Bugatti. Bugatti had no idea this guy was going to be in the auction at all and they probably werent happy when they found out, but it was too late at that point. The rumor is he not only outbid everyone, he also paid off the auctioneer company to let him in on the auction. Super shady.
Anyway, he bought it by paying MILLIONS of dollars (reportedly as much as $18 mil), so no one would ever change its color from the original paint because it would greatly devalue the car.
Fun fact: The details around this car are so secret that no one but the owner and Bugatti knows how much horsepower it has.
That color change was done with lights. This is what the car really looks like...
