Can anybody help me locate touch up paint for wheels for a 2019 a spec?

 

May sound dumb...but I just used some dark gray metallic nail polish...not sure what color it was, but found it easier to find this on my wife's shelf than looking around for codes. It worked well...I need to look to find it, and I'm pretty anal about these things.

And since she nicked the wheel...I'm sure she was happy to donate to the cause.
