> According to major auto paint suppliers, more than 80% of new cars are now grayscale. Black, white, gray, and silver dominate the roads. Reds, blues, and greens in auto production are increasingly rare.

This is biased data: when cars that are not white or black cost 1000 of euros more from the factory, and custom non-preselected colors even more, then people tend to but the cheap colors. Especially when they are corporate lease cars and the corporation doesn’t care about the color.

If car companies want more color, do not charge for it.
