In 2010 and for the 3rd year in a row, black was the most popular color choice for new cars bought or leased in the United States.

One of the best-selling cars of 2010, the Toyota Camry, in black.
A study from the Power Information Network (PIN) and J.D. Power and Associates used retail transaction data from 2010 to identify the most popular new car color choices and the related demographics of car buyers.
More than 20 percent of all new vehicles purchased in 2010 were black, which is up a percentage point from 2009. The average age of buyers of black cars was 45 years old; the youngest average customer age for all color choices during 2010. Black cars sold in an average of 49 days, compared to the average retail rate of 71 days for all cars in 2009.
A few of the other more popular vehicle color choices were silver (17.6%), white (17.7%), and gray (12.1%). Both white and gray color choices increased over last year, but silver saw a decline. Though it ranked fourth on the most bought color list, gray cars sold faster than any other colored cars at an average of 45 days, down from 65 days in 2009.
Red and blue are still among the most popular color choices, but they declined in sales this year to 11.7 percent and 11.6 percent, respectively.
U.S. consumers may be making more subdued color choices, like gray and black, due to the current economic climate. Consumers are in a much more conservative mind set and, as a result, are more likely to choose a more conservative, traditional color as their new car choice. With an upturn of the economy predicted for 2011, more upbeat tones, like silver or blue, could start to move their way back to the top of the list.
