Is the paint color code data plate missing from your car?

paintscratch.com is not very complete with respect to cars earlier than about 1980, and their color patches are notoriously not reliable, either! Plus, the '70/'71 color code system numbering that Porsche used was about the most complex ever devised, with different codes for coupes and Targas!

Looks like Metallic Blue to me, which paintscratch lists only the Targa code for, L8410, but the coupe color would have been L8484 ... per the factory service manual.
