Wow, thats a doozy of a question! I think your best bet would be to pick up a brochure with a printed swatch, and then match it up with a color book (maybe metallic?).
You can get a Color Cue or if you have access to Pantone Guides that would work too. Otherwise I don't have a paint chip to match against, so I can't be more helpful.
