Camera angles, lenses, ambient lighting, chromatic paint can fool the eye. Be it told, the car is probably Toyota's Pearl White.
In the video, it's a Gen 2, in what looks to be Silver Pine Mica (a very cool color!), but Caniac's picture looks like Classic Silver. Maybe he has more than one? Silver Pine Mica wasn't an overly common color, and it only ran from the 2006 to 2009 model years.
I just bought my first Prius C, a 2014 which is a Four...the color is Summer Rain...love it....it has the moon roof, navigation and best of all only 26,000 miles still under factory warranty...the dealer had advertised it as a Prius C Two for 15,999. I used the internet discount which brought the price down to 15,400 and then the manager came out and told me the car had been advertised wrong that it was a Prius C Four with beautiful rims...well he gave me the car for the low price and I have been very happily driving all around.
Based on that video, it looks like Silver Pine Mica (pale green). However, I thought Larry David has a silver Prius?
