Going by what I hear talking to friends and family, they often don't want to choose outside of those range of bland colors as they're worried about resale value. Its probably easier to find a buyer who is OK with a black car than someone who would want metallic purple and gold car or a bright pink car.
Wraps are typically pretty easy to remove. Far easier than removing a paint job.
If you’re that worried about resale value, I’d think that buying a 2-4 year old used car is a way better proposition.
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.
