Fwiw, the explicit advice I got from my parents about cars/houses was to never choose a unique looking one. I was told odd-colored cars are more likely to be broken into, and houses that draw attention (if placed in a neighborhood of otherwise very similar houses) are more likely to be robbed.
So even if my favorite color was an easy option when choosing a car, I'd probably go monochrome as long as that's what the majority of other cars are doing, almost entirely for property crime reasons.
On writing this out, I have absolutely 0 idea how factually-based this is, but it is at least a thing some middle-class Americans tell their kids.
