Can confirm for Japan there are many white cars here. Maybe less then a few years ago, but still the most popular color is definitely white. It's weird to occasionally come across by random chance a whole row of white cars in a parking lot.
Much rarer than white, but still seen surprisingly often are pink cars. Enough that I can say I see more pink cars here in Japan in one day than my entire life in 20th century America. (~ 3 decades or so) Although most of them are a kind of muted, or salmon pink than a hot pink you might be imagining.
