If you're in Canada, take your vehicle to the nearest Car Quest auto supply store. The tech will determine the paint code and can mix it up in a convenient size while you wait.
I recently had the hatch of my Titanium grey 2002 painted. The colour match was close.
I was also told Sherwin Williams can do this - there must be other places too.
If you're only looking for the little paint stick for scratch touch ups, the dealer can order that (I have one).
Good luck, Mark
