Actually, there is an answer.
I've done my nails a few times to match my car, and it was an Essie color. It looks very cool to have the car match the hand on the steering wheel.
I will check through my polishes. I will get back to you.

You know how women always say things like "that's not the right white (or blue, or whatever)"? I blame Essie and their endless color selection . . .
