But what about the interior? Every new car I see/work on at my job seems to have either gray or tan, neither of which are true colors if you ask me. The occasional black upholstery is nice, though.
Both of my '87 Cadillac Broughams have color-coordinated interiors, including such small items as the turn-signal lever, vanity mirrors, et cetera. It is probably more expensive to produce them that way, but I think the effect is well worth it.
Omg, “HitchHiker’s Guide to the Galaxy” flashback!
My uncle had a beige-metallic Ford Taurus. This colour was not only boring, but actually dangerous. Because it blended in so well with the late-winter crud (salt, sand, half-melted snow) that Ontarian roads offer, the paint colour made the car difficult to see during the worst driving times. Result? Far too many close calls to collision.
I do not recommend beige for cars anymore.
If I ever get a car, it’s gonna be white. Then I’ll paint cartoons all over it and apply a clearcoat. 
Porsche accepts paint samples to give you the exact color you want. Of course it is an option that you really have to think about because they do charge extra for non-standard colors.
In 1967, my dad bought a brand-new Chevy Impala - gold. (He’s still got it).
In 2000, I bought a brand-new Chevy Impala - gold. The apple doesn’t fall far from the tree…
I HAVE been seeing some interesting colors on new cars, though. I’ve seen Kias in some bizarre chartreuse color, and Hondas in kind of a metallic burnt-sienna shade. But the best one was the Trans Am Mr Winnie thought about buying in 1995 - green/blue chameleon. Gorgeous. Problem was that…it was on a Trans Am, and we’ve progressed to…less uncomfortable…vehicles.
Get a Corbin Sparrow.
There was a car for sale in Iowa City several years ago that was multi-colored. It was a VW something-or-other display model, and every body section was a different color of paint. It eventually got bought, and I used to see it around town once in a while. zweisamkeit’s Jaguar Black sounds cool.
