Uboat commander
Far be it from me to correct you if you really are a Uboat commander and hence a German speaker, but I didn't think that Lind meant lime. As far as I am aware, the translation in this context is "light green".
The 911 Targa above is definitely Lind Green and the code for it is L275. If it was the Glasurit version, the aux code would have been Y1 I believe.
As for the colour of the 928 I am not sure. Lind Green was available on the 928 according to my research, but in different years to when it was on the 911.
This one's definitely Lind Green:
The Lind colour is known variously as Lind Green, Lindgrun, Light Green and Lint Green. There were two manufacturers of Lind, Glasurit and another whose name I have jotted down somewhere.
