Hi Joe,
i found a thread concerning the colours in the german V11 Forum. They call the green colour "lemon green". And it is made of several coatings or layers ( I do not know the right translation, hope you know what i mean) . Most of the guys who tried to find the right colour code gave up and looked for a (varnisher / painter) who could solve that problem. One of them found the lemon green colour, that PPG has in its program. There it is called "Verde Nacre". Maybe it is helpful for you. If you can speak a bit german maybe this link where the thread was posted is helpful Colour Code lemon green . They are of the opinion that every good (varnisher / painter) is able to mix the right colour.
