The white ones I just found with a Google image search. I found other colors for some views of the car, such as the side view, but the white one was the only one that I was able to find the top view.
I e-mailed Tesla back when I first started the site, but didn't get any response.
Apparently the firmware in the car has all of the images (side and top view), but they're not colored -- they get colorized in software before display, and I don't know the algorithm used to colorize them.
The design studio on Tesla's web site has the side view of the car in all of the present colors, but no top view. And it doesn't have previously available colors (forest green, chocolate brown, navy blue, dolphin gray, titanium silver, and signature red).
