My wife and I were chatting the other day about car colors as we walked about the Hyundai dealer's lot. THe vast majority now are colorless, black, white, or gray. Some of the cars oriented to young folks were rather hideous (to us) garish colors of blue and green.
I noted that cars in France are the same, and have been for eons, it's unusual to see even a red or blue car in France. Cars used to be more colorful here, just regular car cars. Our Hyundai is a very dark blue, it looks black under some lighting.
