I could have sworn there was actually some kind of study that proved this. Cars are sufficiently expensive and longer lived these days that resale value is actually something buyers at least think they need to take into account.

It's actually a little depressing if you're sitting in traffic, just watch the cars go by and see how few of them actually have a unique color. And most of the exceptions are something like an almost gray blue.

For my part I've found new car styling hideous with little difference between brands my entire adult life. Probably for nostalgic reasons I like the sharp geometric shapes of cars from the 1980s which largely disappeared with a focus aerodynamics for gas mileage. So I'm usually satisfied with whatever color is on the lot since I hate the look by default anyway.
