Green oranges? or you mean oranges with leaf?
All oranges are green when they have not reach the optimum point of ripeness, some are still acid and some just have that little green natural colour which is not "commercial" but still good in taste.
However from our experience a customer never understands a fruit can be in its perfect state even when is still a bit green. In Spain for example they give more importance to the "taste" while when we went to Berlin 90% of the fruit exposed in the event (sorry cant remember the name) was "nice looking fruit" (artificial)., so they give a lot of importance to the external aspect there too.
What most european companies do is use artificial ripening process which makes this process faster and also changes dramatically the colour of the fruit just so that is more "commercial"(more orange). What we sell is direct from the orchard, or in other words, as if you took the fruit directly from the tree so the taste is really different to what you can find in supermarkets which is full of additives and residues (so that the fruit lasts longer).
I know the case for Germany since half my family is german and my cousin is living there although I can't speak a single word
