TE Wheels Touch Up Paint Color?

[alext72888]

Was wondering if anyone here has any recommendations for the specific recommendations as to which color and brand works best for touch up paint on the all silver (no black) Trail Edition wheels. I am interested in both spray paint as well as a touch up paint pen/brush combo. Thanks!

So far I've tried rustoleum universal grey and silver. The grey is too dark and the silver is too light. They sell a dark silver online which I might try next.
