Dealership economics also play a big part, at least in the US. If the dealership stocks cars in bright colors, some people will love it, and others will hate it, so selling the car will be hit or miss. If they get lucky they can use the color as a selling point, if they aren't they get stuck with a difficult to sell car at the end of the year. On they other hand, if they stock neutral colors like white, people may not love the color but they won't hate it either - it will rarely make/break a sale. Of course customers can order customized cars, but the dealership will always prefer to sell the stock that they have on hand. So while special ordering a colorful car might be only slightly more expensive than special ordering a white car, special ordering anything for any reason will loose you all negotiating power and cost you thousands of dollars in the final price. I might want a colorful car, but I don't want to pay that much more for a colorful car, so I settle for white.
