According to at least one car salesman I came across when I was looking, females. It was the first question he asked me. (I didn’t buy the car from him.)
My first new car, a 1996 Saturn SL2, was a light-purple jellybean color. I chose it out of their order book, and it was rare enough that I could still pick my car out of the Saturn dealer’s parking lot amid the rows of otherwise identical cars whenever I took it in for servicing.
When that car was totaled in 2002, I went to the same Saturn dealers and tried to get another one just like it. Purple Jellybean was no longer a color option, so I got light blue.
By the time the blue Saturn had had it, they were no longer in business and I went to CarMax to find out what was available that was similar. Color wasn’t important, but as it turned out, it’s a silvery-white Hyundai.
Every time.
I have a titanium (Dark silver metallic) Soul. I wanted a Caribbean Blue, but for utterly unfathomable reasons, that color is only available on the most-basic Plus trim level. They do not offer it on the Exclaim level, or on the Plus with the Audio or Primo packages, which makes no sense since Caribbean Blue is one of their “Designer” colors. Why restrict special “designer” colors to basic models? I would have thought they’d do the opposite - the only way to get a special color is to buy the fancier version of the car.
Years ago, we had a Jeep in “Renaissance Faire Site Dust” tan. It worked - the car would simply go from shiny to not after a weekend at Faire. 
My current car is white. Mostly because I couldn’t find the model I wanted in something like silver or blue, and the white one was available and in good shape. The white is ok in general but it’s a hatchback and the hatch/bumper area tends to stay pretty dirty.
My car’s color (2003 Grand Prix) is “Champagne Beige”. From far away, it never looks dirty and I seldom wash.
I couldn’t be more pleased with the color that I got.
