Most cars are white, black or grey, but have you ever wondered why that is?

CNBC looked into why car colors are so “boring,” and the results might surprise you.

Citing BASF data, the publication says four colors were used on a majority of cars in 2019. White was clear winner at 39% and it was followed by black (16%), grey (13%) and silver (10%).

So why are most vehicles these colors? There are a number of factors at play including the fact that white, black, grey and silver ‘go with everything,’ and are available on virtually every vehicle. The colors also don’t go out of style, unlike some wild choices which might hurt resale values down the road.

In certain markets, customers tend to buy their vehicles off dealership lots rather than having them specially built. This is convenient for buyers, but dealers typically skip wild colors as they want something that appeals to everyone and is easier to sell.

Psychology also plays a role and the video notes that blue is a popular color on electric vehicles. Part of this could be due to the fact that when EVs first started to become popular, some used a specific shade of blue and now consumers might associate blue with electric vehicles.

There are also more shades available thanks to improvements in technology. As an example, the Ram 1500 offers a traditional bright white exterior as well as an ivory white tri-coat option. Another example would be the outgoing Mercedes S-Class which offered multiples shades of black including black, magnetite black metallic and obsidian black metallic.

Of course, some people just like ‘dull’ colors such as white, black and grey.
