Q70S Alloy Wheel Paint Code?

[BobLeo]

I scratched up two of my 20" alloys and I refinished them. However, I couldn't find matching paint for the OEM smoky silver toned finish. Now my right and left side wheels don't match. (I notice and it bugs me, but nobody else sees the mismatch.)

Has anyone found a good paint match by color code or a specific brand and color of rattle-can paint?
