or go to your auto store and find a touch-up stick that's close. Or, to your Ladies Store for a bottle of nail polish, or until you find the right stuff, a coat of clear nail polish.
Or to an auto paint shop, who can mix up a matched pint of what ever you want to cover the wee scratch. Or, email the manufacturer.
My blue MTB got a couple of touch-ups of almost perfect blue nail polish I found in the local flea market.
Looks terrible on my nails, though.
