"Alles ist im grünen Bereich" is literally "Everything is in the green area" - "Everything is under control"...that it is OK.
Although they may seem to be "eccentric" sometimes, German idioms are used by native speakers to cover just about every situation, and heard in all social circles and circumstances. Not only in conversation, but throughout the media and literature.
It is streetwise, colloquial German.
As with all languages some German expressions can be meaningless, even bizarre, if taken word for word, but are used to represent something: a feeling, a description, almost anything.
As idioms make up a large part of everyday speech in Germany, they are sometimes confusing for anyone who has never heard them before and has no idea what they mean.
With their origins lying in its history, literature, religion and traditions, a country's colloquial expressions indicate a great deal about the community's way of thinking, so with Kein Aber - "No But" - No "ifs", "ands" or "buts", here to enjoy, and give you an insight into the German language and Germany's people, are some of the most common sayings used in everyday speech throughout the country.
