Is it just me, or do large vehicles in Japan come in a much bigger, or at least different, variety of colors than they do in the US? I'm thinking mostly of things like buses and large/16-wheel trucks.
In the US, off the top of my head, our 16-wheel trucks mostly have white, red, or black cabs. Every once in awhile, you might get another color, but it seems to be the exception--maybe copper, brown, green? Our buses tend to be simple, too--black, silver, white, red, usually in some combination (provided they're not wrapped for advertising purposes)?
I saw a webcam video of a Japanese highway recently. I saw things like a bright red bus, a bubblegum pink bus, a sunshine yellow truck, an aquamarine truck, a light blue truck, a dark blue truck, a green truck. They weren't outliers, either--there were plenty of white trucks, but maybe 1/3 to 1/4 or so were a color like that, and that proportion probably held for the buses, as well.
I don't know the reason for the difference, but it's really refreshing.
